Power Distribution Diagram
The power supply is based on the ASIC circuit CCONT. The chip consists
of regulators and control circuits providing functions like power up, reset
and watchdog. External buffering is required to provide more current on
some blocks.
The MCU and the CCONT circuits control charging together, detection
being carried out by the CCONT and higher level intelligent control by the
MCU. The MCU measures battery voltage by means of the CCONT. The
CCONT also measures charger voltage, temperature and size of the battery.
Detailed power distribution diagrams are given in Baseband blocks and
RF blocks later in the document.

Technical Summary
The baseband module consists of four asics, CHAPS, CCONT, COBBA–
GJ and MAD2, which take care of the baseband functions of NSM–1.
The baseband is running from a 2.8V power rail, which is supplied by a
power controlling asic. In the CCONT asic there are 6 individually controlled regulator outputs for RF–section and two outputs for the baseband. In addition there is one +5V power supply output (V5V) for flash
programming voltage and other purposes where a higher voltage is needed. The CCONT contains also a SIM interface, which supports both 3V
and 5V SIM–cards. A real time clock function is integrated into the
CCONT, which utilizes the same 32kHz clock supply as the sleep clock. A
backup power supply is provided for the RTC, which keeps the real time
clock running when the main battery is removed. The backup power supply is a rechargable polyacene battery. The backup time with this battery
is minimum of ten minutes.

Technical Documentation
The interface between the baseband and the RF section is handled by a
specific asic. The COBBA asic provides A/D and D/A conversion of the
in–phase and quadrature receive and transmit signal paths and also A/D
and D/A conversions of received and transmitted audio signals to and
from the UI section. The COBBA supplies the analog TXC and AFC signals to rf section according to the MAD DSP digital control and converts
analog AGC into digital signal for the DSP. Data transmission between the
COBBA and the MAD is implemented using a parallel connection for high
speed signalling and a serial connection for PCM coded audio signals.
Digital speech processing is handled by the MAD asic. The COBBA asic
is a dual voltage circuit, the digital parts are running from the baseband
supply VBB and the analog parts are running from the analog supply
VCOBBA.
The baseband supports three external microphone inputs and two external earphone outputs. The inputs can be taken from an internal microphone, a headset microphone or from an external microphone signal
source. The microphone signals from different sources are connected to
separate inputs at the COBBA asic.
System Module
The output for the internal earphone is a dual ended type output capable
of driving a dynamic type speaker. Input and output signal source selection and gain control is performed inside the COBBA asic according to
control messages from the MAD. Keypad tones, DTMF, and other audio
tones are generated and encoded by the MAD and transmitted to the
COBBA for decoding. A buzzer and an external vibra alert control signals
are generated by the MAD with separate PWM outputs.
EMC shieding is implemented using a metallized plastic B–cover with a
conductive rubber seal on the ribs. On the other side the engine is
shielded with a frame having a conductive rubber on the inner walls,
which makes a contact to a ground ring of the engine board and a
ground plane of the UI–board. Heat generated by the circuitry will be conducted out via the PCB ground planes.

Baseband Power Distribution
Functional Description
In normal operation the baseband is powered from the phone‘s battery.
The battery consists of three Nickel Metal Hydride cells. There is also a
possibility to use batteries consisting of one Lithium–Ion cell. An external
charger can be used for recharging the battery and supplying power to
the phone. The charger can be either a standard charger that can deliver
around 400 mA or so called performance charger, which can deliver supply current up to 850 mA.
The baseband contains components that control power distribution to
whole phone excluding those parts that use continuous battery supply.
The battery feeds power directly to three parts of the system: CCONT,
power amplifier, and UI (buzzer and display and keyboard lights). Figure
below shows a block diagram of the power distribution.
The power management circuit CHAPS provides protection agains overvoltages, charger failures and pirate chargers etc. that would otherwise
cause damage to the phone.

Startup Charging
When a charger is connected, the CHAPS is supplying a startup current
minimum of 130mA to the phone. The startup current provides initial
charging to a phone with an empty battery. Startup circuit charges the
battery until the battery voltage level is reaches 3.0V (+/– 0.1V) and the
CCONT releases the PURX reset signal and program execution starts.
Charging mode is changed from startup charging to PWM charging that is
controlled by the MCU software. If the battery voltage reaches 3.55V
(3.75V maximum) before the program has taken control over the charging, the startup current is switched off. The startup current is switched on
again when the battery voltage is sunken 100mV (nominal).

Battery Removal During Charging
Output overvoltage protection is also needed in case the main battery is
removed when charger connected or charger is connected before the battery is connected to the phone.
With a charger connected, if VOUT exceeds VLIM1 (or VLIM2), CHAPS
turns switch OFF until the charger input has sunken below Vpor (nominal
3.0V, maximum 3.4V). MCU software will stop the charging (turn off
PWM) when it detects that battery has been removed. The CHAPS remains in protection state as long as PWM stays HIGH after the output
overvoltage situation has occured.

Different PWM Frequencies ( 1Hz and 32 Hz)
When a travel charger (2– wire charger) is used, the power switch is
turned ON and OFF by the PWM input when the PWM rate is 1Hz. When
PWM is HIGH, the switch is ON and the output current Iout = charger current – CHAPS supply current. When PWM is LOW, the switch is OFF and
the output current Iout = 0. To prevent the switching transients inducing
noise in audio circuitry of the phone soft switching is used.
The performance travel charger (3– wire charger) is controlled with PWM
at a frequency of 32Hz. When the PWM rate is 32Hz CHAPS keeps the
power switch continuously in the ON state.

Supply Voltage Regulators
The heart of the power distrubution is the CCONT. It includes all the voltage regulators and feeds the power to the whole system. The baseband
digital parts are powered from the VBB regulator which provides 2.8V
baseband supply. The baseband regulator is active always when the
phone is powered on. The VBB baseband regulator feeds MAD and memories, COBBA digital parts and the LCD driver in the UI section. There is
a separate regulator for a SIM card. The regulator is selectable between
3V and 5V and controlled by the SIMPwr line from MAD to CCONT. The
COBBA analog parts are powered from a dedicated 2.8V supply VCOBBA. The CCONT supplies also 5V for RF and for flash VPP. The CCONT
contains a real time clock function, which is powered from a RTC backup
when the main battery is disconnected.

Power up with a charger
When the charger is connected CCONT will switch on the CCONT digital
voltage as soon as the battery voltage exeeds 3.0V. The reset for
CCONT’s digital parts is released when the operating voltage is stabilized
( 50 us from switching on the voltages). Operating voltage for VCXO is
also switched on. The counter in CCONT digital section will keep MAD in
reset for 62 ms (PURX) to make sure that the clock provided by VCXO is
stable. After this delay MAD reset is relased, and VCXO –control
(SLEEPX) is given to MAD. The diagram assumes empty battery, but the
situation would be the same with full battery:
When the phone is powered up with an empty battery pack using the
standard charger, the charger may not supply enough current for standard powerup procedure and the powerup must be delayed.
Power Up With The Power Switch (PWRONX)
Technical Documentation
When the power on switch is pressed the PWRONX signal will go low.
CCONT will switch on the CCONT digital section and VCXO as was the
case with the charger driven power up. If PWRONX is low when the 64
ms delay expires, PURX is released and SLEEPX control goes to MAD. If
PWRONX is not low when 64 ms expires, PURX will not be released, and
CCONT will go to power off ( digital section will send power off signal to

Acting Dead
If the phone is off when the charger is connected, the phone is powered
on but enters a state called ”acting dead”. To the user the phone acts as if
it was switched off. A battery charging alert is given and/or a battery
charging indication on the display is shown to acknowledge the user that
the battery is being charged.
Active Mode
System Module
In the active mode the phone is in normal operation, scanning for channels, listening to a base station, transmitting and processing information.
All the CCONT regulators are operating. There are several substates in
the active mode depending on if the phone is in burst reception, burst
transmission, if DSP is working etc..
Sleep Mode
In the sleep mode, all the regulators except the baseband VBB, VCOBBA,
and the SIM card VSIM regulators are off. Sleep mode is activated by the
MAD after MCU and DSP clocks have been switched off. The voltage regulators for the RF section are switched off and the VCXO power control,
VCXOPwr is set low. In this state only the 32 kHz sleep clock oscillator in
CCONT is running. The flash memory power down input is connected to
the ExtSysResetX signal, and the flash is deep powered down during the
sleep mode.
The sleep mode is exited either by the expiration of a sleep clock counter
in the MAD or by some external interrupt, generated by a charger connection, key press, headset connection etc. The MAD starts the wake up
sequence and sets the VCXOPwr and ExtSysResetX control high. After
VCXO settling time other regulators and clocks are enabled for active
mode.
If the battery pack is disconnect during the sleep mode, the CCONT pulls
the SIM interface lines low as there is no time to wake up the MCU.

Charging can be performed in any operating mode. The charging algorithm is dependent on the used battery technology. The battery type is in-

dicated by a resistor inside the battery pack. The resistor value corresponds to a specific battery capacity. This capacity value is related to the
battery technology as different capacity values are achieved by using different battery technology.
The battery voltage, temperature, size and current are measured by the
CCONT controlled by the charging software running in the MAD.
The power management circuitry controls the charging current delivered
from the charger to the battery. Charging is controlled with a PWM input signal, generated by the CCONT. The PWM pulse width is controlled by the
MAD and sent to the CCONT through a serial data bus. The battery voltage
rise is limited by turning the CHAPS switch off when the battery voltage has
reached 4.2V (LiIon) or 5.2V (NiMH, 5V in call mode). Charging current is
monitored by measuring the voltage drop across a 220mohm resistor.
Power Off
The baseband is powered down by:
Technical Documentation
1.Pressing the power key, that is monitored by the MAD, which
starts the power down procedure.
2.If the battery voltage is dropped below the operation limit, either by not charging it or by removing the battery.
3.Letting the CCONT watchdog expire, which switches off all
CCONT regulators and the phone is powered down.
4.Setting the real time clock to power off the phone by a timer.
The RTC generates an interrupt signal, when the alarm is gone
off. The RTC interrupt signal is connected to the PWRONX line
to give a power off signal to the CCONT just like the power key.
The power down is controlled by the MAD. When the power key has been
pressed long enough or the battery voltage is dropped below the limit the
MCU initiates a power down procedure and disconnects the SIM power.
Then the MCU outputs a system reset signal and resets the DSP. If there is
no charger connected the MCU writes a short delay to CCONT watchdog
and resets itself. After the set delay the CCONT watchdog expires, which
activates the PURX and all regulators are switched off and the phone is
powered down by the CCONT.
If a charger is connected when the power key is pressed the phone enters into the acting dead mode.
Watchdog
Page 3–30
The Watchdog block inside CCONT contains a watchdog counter and
some additional logic which are used for controlling the power on and
power off procedures of CCONT. Watchdog output is disabled when
WDDisX pin is tied low. The WD-counter runs during that time, though.
Watchdog counter is reset internally to 32s at power up. Normally it is reset by MAD writing a control word to the WDReg.

The baseband supports three microphone inputs and two earphone outputs. The inputs can be taken from an internal microphone, a headset microphone or from an external microphone signal source. The microphone
signals from different sources are connected to separate inputs at the
COBBA–GJ asic. Inputs for the microphone signals are differential type.
The MIC1 inputs are used for a headset microphone that can be connected directly to the system connector. The internal microphone is connected to MIC2 inputs and an external pre–amplified microphone (handset/handfree) signal is connected to the MIC3 inputs. In COBBA there are
also three audio signal outputs of which dual ended EAR lines are used
for internal earpiece and HF line for accessory audio output. The third audio output AUXOUT is used only for bias supply to the headset microphone. As a difference to DCT2 generation the SGND ( = HFCM at COBBA) does not supply audio signal (only common mode). Therefore there
are no electrical loopback echo from downlink to uplink.
The output for the internal earphone is a dual ended type output capable
of driving a dynamic type speaker. The output for the external accessory
and the headset is single ended with a dedicated signal ground SGND.
Input and output signal source selection and gain control is performed inside the COBBA–GJ asic according to control messages from the MAD2.
Keypad tones, DTMF, and other audio tones are generated and encoded
by the MAD2 and transmitted to the COBBA–GJ for decoding.

Analog Audio Accessory Detection
In XEAR signal there is a 47 kW pullup in the transceiver and 6.8 kW
pull–down to SGND in accessory. The XEAR is pulled down when an
accessory is connected, and pulled up when disconnected. The XEAR is
connected to the HookDet line (in MAD), an interrupt is given due to both
connection and disconnection. There is filtering between XEAR and
HookDet to prevent audio signal giving unwanted interrupts.
External accessory notices powered–up phone by detecting voltage in
XMIC line. In Table 23 there is a truth table for detection signals.

Headset Detection
The external headset device is connected to the system connector, from
which the signals are routed to COBBA headset microphone inputs and
earphone outputs. In the XMIC line there is a (47 + 2.2) kW pullup in the
transceiver. The microphone is a low resistancepulldown compared to
the transceiver pullup.
When there is no call going, the AUXOUT is in high impedance state and
the XMIC is pulled up. When a headset is connected, the XMIC is pulled
down. The XMIC is connected to the HeadDet line (in MAD), an interrupt
is given due to both connection and disconnection. There is filtering between the XMIC and the HeadDet to prevent audio signal giving unwanted interrupts (when an accessory is connected).
In the XEAR line there is a 47 kW pullup in the transceiver. The earphone
is a low resistance pulldown compared to the transceiver pullup. When a
remote control switch is open, there is a capacitor in series with the earphone, so the XEAR (and HookDet) is pulled up by the phone. When the
switch is closed, the XEAR (and HookDet) is pulled down via the earphone. So both press and release of the button gives an interrupt.
During a call there is a bias voltage (1.5 V) in the AUXOUT, and the
HeadDet cannot be used. The headset interrupts should to be disabled
during a call and the EAD line (AD converter in CCONT) should be polled
to see if the headset is disconnected.

Internal Audio Connections
The speech coding functions are performed by the DSP in the MAD2 and
the coded speech blocks are transferred to the COBBA–GJ for digital to
analog conversion, down link direction. In the up link direction the PCM
coded speech blocks are read from the COBBA–GJ by the DSP.
There are two separate interfaces between MAD2 and COBBA–GJ: a
parallel bus and a serial bus. The parallel bus has 12 data bits, 4 address
bits, read and write strobes and a data available strobe. The parallel interface is used to transfer all the COBBA–GJ control information (both the
RFI part and the audio part) and the transmit and receive samples. The
serial interface between MAD2 and COBBA–GJ includes transmit and receive data, clock and frame synchronisation signals. It is used to transfer
the PCM samples. The frame synchronisation frequency is 8 kHz which
indicates the rate of the PCM samples and the clock frequency is 1 MHz.
COBBA is generating both clocks.
4–wire PCM Serial Interface
Technical Documentation
The interface consists of following signals: a PCM codec master clock
(PCMDClk), a frame synchronization signal to DSP (PCMSClk), a codec
transmit data line (PCMTX) and a codec receive data line (PCMRX). The
COBBA–GJ generates the PCMDClk clock, which is supplied to DSP SIO.
The COBBA–GJ also generates the PCMSClk signal to DSP by dividing
the PCMDClk. The PCMDClk frequency is 1.000 MHz and is generated
by dividing the RFIClk 13 MHz by 13. The COBBA–GJ further divides the
PCMDClk by 125 to get a PCMSClk signal, 8.0 kHz.

Alert Signal Generation
A buzzer is used for giving alerting tones and/or melodies as a signal of
an incoming call. Also keypress and user function response beeps are
generated with the buzzer. The buzzer is controlled with a BuzzerPWM
output signal from the MAD. A dynamic type of buzzer must be used
since the supply voltage available can not produce the required sound
pressure for a piezo type buzzer. The low impedance buzzer is connected
to an output transistor that gets drive current from the PWM output. The
alert volume can be adjusted either by changing the pulse width causing
the level to change or by changing the frequency to utilize the resonance
frequency range of the buzzer.
A vibra alerting device is used for giving silent signal to the user of an incoming call. The device is controlled with a VibraPWM output signal from
the MAD2. The vibra alert can be adjusted either by changing the pulse
width or by changing the pulse frequency. The vibra device is not inside
the phone, but in a special vibra battery.

System Module
The MAD2 operates from a 13 MHz system clock, which is generated
from the 13Mhz VCXO frequency. The MAD2 supplies a 6,5MHz or a
13MHz internal clock for the MCU and system logic blocks and a 13MHz
clock for the DSP, where it is multiplied to 52 MHz DSP clock. The system
clock can be stopped for a system sleep mode by disabling the VCXO
supply power from the CCONT regulator output. The CCONT provides a
32kHz sleep clock for internal use and to the MAD2, which is used for the
sleep mode timing. The sleep clock is active when there is a battery voltage available i.e. always when the battery is connected.

Memories
The MCU program code resides in an external flash program memory,
which size is 16 Mbits (1024kx16bit). The MCU work (data) memory size
is 1 Mbits (128kx8bit). A serial EEPROM is used for storing the system
and tuning parameters, user settings and selections, a scratch pad and a
short code memory. The EEPROM size is 128kbits (16kx8bit).
The BusController (BUSC) section in the MAD decodes the chip select
signals for the external memory devices and the system logic. BUSC controls internal and external bus drivers and multiplexers connected to the
MCU data bus. The MCU address space is divided into access areas with
separate chip select signals. BUSC supports a programmable number of
wait states for each memory range.
Program Memory
The MCU program code resides in the program memory. The program
memory size is 16 Mbits (1024kx16bit).
System Module
The flash memory has a power down pin that should be kept low, during
the power up phase of the flash to ensure that the device is powered up
in the correct state, read only. The power down pin is utilized in the system sleep mode by connecting the ExtSysResetX to the flash power down
pin to minimize the flash power consumption during the sleep.
SRAM Memory
The work memory is a static ram of size 1Mbit (128kx8) in a shrink
TSOP32 package. The work memory is supplied from the common baseband VBB voltage and the memory contents are lost when the baseband
voltage is switched off. All retainable data should be stored into the EEPROM (or flash) when the phone is powered down.
EEPROM Memory
An EEPROM is used for a nonvolatile data memory to store the tuning
parameters and phone setup information. The short code memory for
storing user defined information is also implemented in the EEPROM.
The EEPROM size is 128kbits. The memory is accessed through a serial
bus and the default package is SO8.

MCU Memory Map
MAD2 supports maximum of 4GB internal and 4MB external address
space. External memories use address lines MCUAd0 to MCUAd21 and
16–bit databus. The BUSC bus controller supports 8– and 16–bit access
for byte, double byte, word and double word data. Access wait state 2
and used databus width can be selected separately for each memory
block.
Flash Programming
The phone have to be connected to the flash loading adapter FLA–5 so
that supply voltage for the phone and data transmission lines can be supplied from/to FLA–5. When FLA–5 switches supply voltage to the phone,
the program execution starts from the BOOT ROM and the MCU investigates in the early start–up sequence if the flash prommer is connected.
This is done by checking the status of the MBUS–line. Normally this line
is high but when the flash prommer is connected the line is forced low by
the prommer.
Technical Documentation
The flash prommer serial data receive line is in receive mode waiting for
an acknowledgement from the phone. The data transmit line from the
baseband to the prommer is initially high. When the baseband has recognized the flash prommer, the TX–line is pulled low. This acknowledgement is used to start to toggle MBUS (FCLK) line three times in order that
MAD2 gets initialized. This must be happened within 15 ms after TX line
is pulled low. After that the data transfer of the first two bytes from the
flash prommer to the baseband on the RX–line must be done within 1 ms.
When MAD2 has received the secondary boot byte count information, it
forces TX line high. Now, the secondary boot code must be sent to the
phone within 10 ms per 16 bit word. If these timeout values are exceeded,
the MCU (MAD2) starts normal code execution from flash. After this, the
timing between the phone and the flash prommer is handled with dummy
bites.
A 3V programming voltage is supplied inside the transceiver from the battery voltage with a switch mode regulator (3V/30mA) of the CCONT. The
3V is connected to VPP pin of the flash through the UI board.
COBBA–GJ
The COBBA–GJ provides an interface between the baseband and the
RF–circuitry. COBBA–GJ performs analogue to digital conversion of the
receive signal. For transmit path COBBA_GJ performs digital to analogue
conversion of the transmit amplifier power control ramp and the in–phase
and quadrature signals. A slow speed digital to analogue converter will
provide automatic frequency control (AFC).

Infrared Transceiver Module
The module is activated with an IRON signal by the MAD, which supplies
power to the module. The IR datalines are connected to the MAD accessory interface AccIf via FBUS. The RX and TX lines are separated from
FBUS by three–state buffers, when the IR–module is switched off. The
AccIf in MAD performs pulse encoding and shaping for transmitted data
and detection and decoding for received data pulses.
The data is transferred over the IR link using serial data at speeds 9.6,
19.2, 38.4, 57.6 or 115.2 kbits/s, which leads to maximum throughput of
92.160 kbits/s. The used IR module complies with the IrDA 1.0 specification (Infra Red Data Association), which is based on the HP SIR (Hewlett–
Packard‘s Serial Infra Red) consept.
Following figure gives an example of IR transmission pulses. In IR transmission
a light pulse correspondes to 0–bit and a ”dark pulse” correspondes to 1–bit.

The FBUS cannot be used for external accessory communication when the infrared mode is selected, as IR communication reserves the FBUS completely.
Real Time Clock
Requirements for a real time clock implementation are a basic clock
(hours and minutes), a calender and a timer with alarm and power on/off
–function and miscellaneous calls. The RTC will contain only the time
base and the alarm timer but all other functions (e.g. calendar) will be implemented with the MCU software. The RTC needs a power backup to
keep the clock running when the phone battery is disconnected. The
backup power is supplied from a rechargable polyacene battery that can
keep the clock running some ten minutes. If the backup has expired, the
RTC clock restarts after the main battery is connected. The CCONT
keeps MCU in reset until the 32kHz source is settled (1s max).
startbitstopbit10100110
The CCONT is an ideal place for an integrated real time clock as the asic
already contains the power up/down functions and a sleep control with
the 32kHz sleep clock, which is running always when the phone battery is
connected. This sleep clock is used for a time source to a RTC block.

RTC backup battery charging
CHAPS has a current limited voltage regulator for charging a backup battery. The regulator derives its power from VOUT so that charging can take
place without the need to connect a charger. The backup battery is only
used to provide power to a real time clock when VOUT is not present so it
is important that power to the charging circuitry is derived from VOUT and
that the charging circuitry does not present a load to the backup battery
when VOUT is not present.
It should not be possible for charging current to flow from the backup battery into VOUT if VOUT happens to be lower than VBACK. Charging current will gradually diminish as the backup battery voltage reaches that of
the regulation voltage.
Vibra Alerting Device
A vibra alerting device is used for giving silent signal to the user of an incoming call. The device is not placed in the phone but it will be added to a

Functional Description
RF block diagram has conventional dual conversion receiver for GSM and
triple conversion receiver for DCS1800. Both receivers use upper side LO
drive in the first RF mixer, after that lower side LO drive is used. Because
of this there is no need to change I/Q phasing in baseband when receiving band is changed between DCS and GSM.The two receiver chains are
combined in 73 MHZ IF so they use same rx–chain from that point down
to 13MHz A–D converter. In transmitter side there are two image rejection
upconversion mixers,one for GSM and one for DCS 1800, for the final
TX–frequency. Both use upper side LO drive. Because there is only one
external antenna connector used, common for both bands, dualband duplex filter has one common antenna input/output.
Technical Documentation
Architecture contains three ICs. Most of the functions are horizontally and
vertically integrated. UHF functions except power amplifier and VCO are
integrated into CRFU3, which is a RF–IC using bipolar process
(Ft=25GHz) suitable for 2GHz LNA– and mixer–functions. CRFU3 also
includes divide–by–two prescaler for UHF–VCO. Using this divider it is
possible to use only one UHF–VCO running at 2GHz and UHF synthesizer in SUMMA can still use 1GHz LO signal with both systems. The selection between GSM and DCS1800 operation modes in CRFU3 is done with
mode selection signal derived from MAD IC in baseband. This signal controls the biasing circuitries of the different RF blocks in CRFU3 so that
GSM blocks and DCS1800 blocks are not active at the same time. This
way there is no need for extra voltage regulators and the same CCONT
regulator–IC can be used as in singlebander DCT3 products
Most of the RF–functions are in SUMMA which is a BiCMOS–circuit.
SUMMA is an IF–circuit including IQ–modulator with two buffered outputs,
one for GSM TX IF and one for DCS1800 TXIF, PLLs for VHF– and
UHF–synthesizers, RX AGC amplifier and RX mixer for 13 MHz downconversion. It also includes two operational amplifiers for TX power control loop. There is one common input for power detector voltage and one
for TXC–control and two outputs for power control of the PA, one for
GSM PA and one for DCS PA. The selection between GSM and
DCS1800 operation modes is done via serial bus of SUMMA.
Page 3–50
Power amplifiers are also ASICs, called MMIC ( monolithic microwave
integrated circuit ). There are two separate PAs, one for GSM and one for
DCS1800. Both PAs include input and interstage matchings. Output
matching networks are external for both systems. TX gaincontrol is also
integrated into these chips.

Regulators
Transceiver has got a multi function power management IC, which contains among other functions, also 7 pcs of 2.8 V regulators. All regulators
can be controlled individually with 2.8 V logic directly or through control
register. Direct controls are used to get fast switching, because regulators
are used to enable RF–functions.
Use of the regulators can be seen in the power distribution diagram.
CCONT also provides 1.5 V reference voltage for SUMMA ( and for
DACs and ADCs in COBBA too ).
Control Signals
All control signals are coming from MAD and they are 2.8 V logic signals.
Technical Documentation
Frequency synthesizers
Both UHF– and VHF–VCO are locked with PLLs into stable frequency
source, which is a VCTCXO–module ( voltage controlled temperature
compensated crystal oscillator ). Using VCTCXO, it is possible to leave
the center frequency and control curve slope calibration away in production if needed.This VCTCXO is running at 13 MHz. Temperature effect is
controlled with AFC ( automatic frequency control ) voltage in order to
maintain VCTCXO locked into frequency of the base station. AFC is generated by baseband with a 11 bit DAC in COBBA–ASIC.
UHF PLL is located in SUMMA. There are 64/65 (P/P+1) prescaler, N–
and A–divider, reference divider, phase detector and charge pump for the
external loop filter. UHF local signal is generated by dividing the UHF–
VCO signal (there is only one UHF–VCO module, that is common for both
systems, running at 2GHz) by two in CRFU3 prescaler and from that the
signal is fed to SUMMA prescaler. Prescaler is a dual modulus divider.
Output of the prescaler is fed to N– and A–divider, which produce the input to phase detector. Phase detector compares this signal to reference
signal, which is divided with reference divider from VCTCXO output. Output of the phase detector is connected into charge pump, which charges
or discharges integrator capacitor in the loop filter depending on the
phase of the measured frequency compared to reference frequency. Loop
filter filters out the pulses and generates DC to control the frequency of
UHF–VCO. Loop filter defines step response of the PLL ( settling time )
and effects to stability of the loop, that’s why integrator capacitor has got
a resistor for phase compensation. Other filter components are for sideband rejection.
Dividers are controlled via serial bus. SDATA is for data, SCLK is serial
clock for the bus and SENA1 is a latch enable, which stores new data into
dividers.

VHF PLL is also located into SUMMA. There is 16/17 ( P/P+1 ) dual modulus prescaler, N– and A–dividers, reference divider, phase detector and
charge pump for the loop filter. VHF local signal is generated with a VHF
VCO. VHF PLL is common for GSM and DCS1800. VHF PLL is locked
on fixed frequency, 480Mhz in GSM and DCS1800 RX mode. In
DCS1800 TX mode VHF local signal is 480Mhz in every odd numbered
channel and 480.4Mhz in every even numbered channel. Also UHF local
frequency in DCS1800 TX mode changes only in every second channel
by 400kHz. In every other mode ( GSM, DCS1800 RX ) UHF local signal
spacing is 200kHz, so it follows the channel spacing.

Receiver
GSM frontend
GSM receiver is a dual conversion linear receiver. This frontend in
CRFU3 rf–asic is activated with mode–selection signal set to high–state.
Received RF–signal from the antenna is fed via the duplex filter to LNA
(low noise amplifier) in CRFU3. Active parts (RF–transistor and biasing
and AGC–step circuitry) are integrated into this chip. Input and output
matching networks are external. Gain selection is done with PDATA0 control. Gain step in LNA is activated when RF–level in antenna is about –47
dBm. After the LNA,amplified signal (with low noise level) is fed to bandpass filter, which is a SAW–filter (SAW, surface acoustic wave). Duplex
filter and RX interstage bandpass filters together define, how good are the
blocking characteristics against spurious signals outside receive band
and the protection against spurious responses, mainly the image of the
first mixer.
This bandpass filtered signal is then mixed down to 73 MHz, which is first
GSM intermediate frequency. 1st mixer is located into CRFU3 ASIC. This
integrated mixer is a double balanced Gilbert cell. It is driven balanced.
All active parts and biasing are integrated and matching components are
external. Because this is an axtive mixer it also amplifies IF–frequency.
Also local signal buffering is integrated and upper side injection is used.
First local signal is generated with UHF–synthesizer.

DCS1800 frontend
DCS receiver is a triple conversion linear receiver.This frontend in CRFU3
rf–asic is activated with mode–selection signal set to low–state. Received
RF–signal from the antenna is fed via the duplex filter to LNA (low noise
amplifier) in CRFU3. Active parts (RF–transistor and biasing and AGC–
step circuitry) are integrated into this chip. Input and output matching networks are external. Gain selection is done with PDATA0 control. Gain step
in LNA is activated when RF–level in antenna is about –47 dBm. After the
LNA amplified signal (with low noi–se level) is fed to bandpass filter,
which is a SAW. Duplex filter and RX interstage bandpass filters together
define, how good are the blocking characteristics against spurious signals
outside receive band and the protection against spurious responses.
This bandpass filtered signal is then mixed down to 193 MHz IF, which is
first DCS intermediate frequency. 1st mixer is in CRFU3 ASIC. This integrated mixer is a double balanced Gilbert cell. It is driven balanced. All
active parts and biasing are integrated and matching components are external. Because this is an axtive mixer it also amplifies IF–frequency. Also
local signal buffering is integrated and upper side injection is used. First
local signal is generated with UHF–synthesizer.There is a balanced LC–
bandpass filter in the output of the first mixer which e.g. attenuates the
critical 167MHz spurious and 156,5 MHz half–if frequency. It also
matches impedance of 193MHz output to following stage input. After this
filter, the 193MHz IF–signal is mixed down to 73MHz IF, which is second

DCS intermediate frequency. This VHF–mixer is also double balanced
Gilbert cell and is located into CRFU3. Lower side LO signal is used. This
120MHz lo signal is got from SUMMA–ASIC where it is derived by dividing 480MHz VHFLO signal by four.There is an external lowpass filter for
this 120MHz lo signal which attenuates the harmonics (especially
240MHz) so that the critical mixing spurious will be attenuated.
Common Receiver parts for GSM and DCS1800
After the GSM RX–mixer and DCS VHF–mixer, the RX–signal path is
common for both systems. This 73MHz IF–signal is bandpass filtered
with a selective SAW–filter. From the mixers‘ outputs to IF–circuit input of
SUMMA–ASIC, signal path is balanced. IF–filter provides selectivity for
channels greater than +/–200 kHz. Also it attenuates image frequency of
the following mixer and intermodulating signals. Selectivity is required in
this place, because of needed linearity and without filtering adjacent
channel interferers would be on too high signal level for the stages following.
System Module
Next stage in the receiver chain is an AGC–amplifier. It is integrated into
SUMMA–ASIC. AGC gain control is analog. Control voltage for the AGC
is generated with DA–converter in COBBA–ASIC in baseband. AGC–
stage provides accurate gain control range (min. 57 dB) for the receiver.
After the AGC–stage, the 73MHz if–signal is mixed down to 13MHz. The
needed 60MHz LO signal is generated in SUMMA by dividing VHF–synthesizer output ( 480 MHz ) by eight .
The following IF–filter is a ceramic bandpass filter at 13 MHz. It attenuates adjacent channels, except for +/– 200 kHz there is not much attenuation. Those +/– 200 kHz interferers are filtered digitally by the baseband.
Because of this RX DACs has to be so good, that there is enough dynamic range for the faded 200 kHz interferer. Also the whole RX has to be
able to handle signal levels in a linear way. After the 13 MHz filter there is
a buffer for the IF–signal, which also converts and amplifies single ended
signal from filter to balanced signal for the buffer and AD–converters in
COBBA. Buffer in SUMMA has voltage gain of 36 dB and buffer gain setting in COBBA is 0 dB. It is possible to set gainstep ( 9.5 dB ) into COBBA
via control bus, if needed.

Transmitter
Transmitter chain consists of IQ–modulator which is common for both
systems, two image rejection upconversion mixers, two power amplifiers
and a power control loop.
GSM transmitter
I– and Q–signals are generated by baseband in COBBA–ASIC. After post
filtering (RC–network) they are fed into IQ–modulator in SUMMA. It generates modulated TX IF–frequency, which is VHF–synthesizer output divided by four, meaning 120 MHz. The TX–amplifier in SUMMA has two
selectable gain levels. Output is set to maximum via control register of
SUMMA. After SUMMA there is a bandpass LC–filter for noise and harmonic filtering before the signal is fed for upconversion into final TX–frequency in CRFU3. Upconversion mixer in CRFU3 is so called image rejection mixer. It is able to attenuate unwanted sideband in the upconverter
output. Mixer itself is a double balanced Gilbert cell. Phase shifters required for image rejection are also integrated. Local signal needed in upconversion is generated by the UHF–synthesizer, but buffers for the mixer
are integrated into CRFU3. Output of the upconverter is single ended and
requires external matching to 50 ohm impedance.
Technical Documentation
Next stage is TX interstage filter, which attenuates unwanted signals from
the upconverter, mainly LO–leakage and image frequency from the upconverter. Also it attenuates wideband noise. This bandpass filter is a
SAW–filter.
After interstage filter, tx–signal is fed to GSM input of the PA, which is a
MMIC consisting of three amplifier stages and interstage matchings. It
has 50 ohm input, but output requires an external matching network.
Gain control is integrated into PA and it is controlled with a power control
loop. PA has over 35 dB power gain and it is able to produce 3.0 W into
output with 0 dBm input level. Gain control range is over 35 dB to get desired power levels and power ramping up and down. Harmonics generated by the nonlinear PA (class AB) are filtered out with the matching network and lowpass/bandstop filtering in the duplexer. Bandstop is required
because of wideband noise located on RX–band. There is a directional
coupler connected between PA output and duplex filter input.
DCS1800 transmitter
I– and Q–signal routes from COBBA–ASIC, post filtering and IQ–modulator in SUMMA are common with GSM. In DCS1800, TX–IF frequency is
generated by using VHF synthesizer frequency divided by two, meaning
240 MHz. The TX–amplifier in SUMMA has two selectable gain levels.
Output (single–ended) is set to maximum via control register of SUMMA.
After SUMMA there is a lowpass LC–filter for harmonic filtering before the
signal is fed for upconversion into final TX–frequency in CRFU3. Upconversion mixer for DCS is also image rejection mixer. Local signal needed
in upconversion is generated by the UHF–synthesizer and buffers for the

mixer are integrated into CRFU3. Output of the upconverter is single ended and requires external matching to 50 ohm impedance.
Next stage is TX interstage filter, which attenuates unwanted signals from
the upconverter, mainly LO–leakage and image frequency from the upconverter. Also it attenuates wideband noise. This bandpass filter is a
SAW filter.
After interstage filter, tx–signal is fed to the input of DCS MMIC PA. It is
50 ohm input, but output requires an external matching network. DCS
MMIC PA contains three amplifier stages and interstage matchings. The
PA has over 33 dB power gain and it is able to produce 1.9 W into output
with 0 dBm input level. Gain control range is over 35 dB to get desired
power levels and power ramping up and down. Output matching and duplexer are used for same purposes as in GSM. There is a directional coupler connected between PA output and duplex filter input.
Transmitter power control for GSM and DCS1800
Power control circuitry consists of PA‘s gain control stage, power detector
in the PA output and error amplifier in SUMMA–ASIC. There is a directional coupler connected between PA output and duplex filter in both
chains, but the power sensing line and detector are common for both
bands. It takes a sample from the forward going power with certain ratio.
This signal is rectified in a schotky–diode and it produces a DC–signal after RC–filtering. This peak–detector is linear on absolute scale, except it
saturates on very low and high power levels, so it produces a S–shape
curve.
System Module
This detected voltage is compared in the error–amplifier in SUMMA to
TXC–voltage, which is generated by DA–converter in COBBA. The output
of the error amplifier is fed to PA gaincontrol stage. Because also gaincontrol characteristics in PA are linear in absolute scale, control loop defines a voltage loop, when closed. Closed loop tracks the TXC–voltage.
4
TXC has a raised cosine form (cos
– function), which reduces switching
transients, when pulsing power up and down. Because dynamic range of
the detector is not wide enough to control the power (actually RF output
voltage) over the whole range, there is a control named TXP to work under detected levels. Burst is enabled and set to rise with TXP until the
output level is high enough for the feedback loop to work. Loop controls
the output power via the control pin in PA MMIC to the desired output level and burst has the waveform of TXC–ramps. Because feedback loops
could be unstable, this loop is compensated with a dominating pole. This
pole decreases gain on higher frequencies to get phase margins high
enough.

AGC strategy
AGC–amplifier is used to maintain output level of the receiver to COBBA
A/D–converters almost constant AGC has to be set before each received
burst and pre–monitoring is used for this. Receiver is switched on roughly xxx us before the burst begins, DSP measures received signal level
and adjusts RXC, which controls RX AGC–amplifier or it switches off the
LNA with PDATA0 control line if the signal level is too high. This pre–monitoring is done in three phases and this sets the settling times for RX
AGC. Pre–monitoring is required because of linear receiver, received signal must be in full swing, no clipping is allowed and because DSP doesn’t
know, what is the level going to be in next burst.
There is at least 57 dB accurate gain control ( continous, analog ) and
one digital step in LNA. It is typically about 31...33 dB.
RSSI must be measured on range –48...–110 dBm. After –48 dBm level
MS reports to base station the same reading.
Because of RSSI–requirements, gain step in LNA is used roughly on –47
dBm RF–level and up to –10 dBm input RF–level accurate AGC is used
to set RX output level. LNA is ON (PDATA0 = ”0”) below –47 dBm. From
–47 dBm down to –95 dBm this accurate AGC in SUMMA is used to adjust the gain to desired value. RSSI–function is in DSP, but it works out
received signal level by measuring RX IQ–level after all selectivity filtering
(meaning IF–filters, Σ∆±converter and FIR–filter in DSP). So 48 dB accurate AGC dynamic range is required. Remaining 10 dB is for gain variations in RX–chain ( for calibration ). Below –95 dBm RF–levels, output
level of the receiver drops dB by dB. At –95 dBm level output of the receiver gives 50 mVpp. This is the target value for DSP. Below this it drops
down to about 9 mVpp @ –110 dBm RF–level.
System Module
This strategy is chosen because AGC in SUMMA has to start to roll off
early enough, so that it won’t saturate in selectivity tests. Also we can‘t
start too early , i.e. with too low receiving levels , because then we will
sacrifice the signal to noise ratio and it would require more accurate AGC
dynamic range. 50 mVpp target level is set, because RX–DA converter
will saturate at 1.4 Vpp. This over 28 dB headroom is required to have
margin for +/– 200 kHz faded adjacent channel (ca. 19 dB) and extra 9
dB for pre–monitoring.
Production calibration is done with two RF–levels, LNA gain step is not
calibrated. Gain changes in the receiver are taken off from the dynamic
range of accurate AGC. Variable gain stage in SUMMA is temperature
compensated so that there should be good enough margin in AGC range
to cover the gain changes in frontend of the receiver.

AFC function
AFC is used to lock the transceivers clock to frequency of the base station. AFC–voltage is generated in COBBA with 11 bit AD–converter.
There is a RC–filter in AFC control line to reduce the noise from the converter. Settling time requirement for the RC–network comes from signalling, how often PSW (pure sine wave) slots occur. They are repeated every 10 frames, meaning that there is PSW in every 46 ms. AFC tracks
base station frequency continously, so transceiver has a stable frequency,
because there are no rapid changes in VCTCXO –output (changes due
to temperature are relatively slow). Settling time requirement comes also
from the start up–time allowed. When transceiver is in sleep mode and
”wakes” up to receive mode, there is only about 5 ms for the AFC–voltage to settle. When the first burst comes in system clock has to be settled
into +/– 0.1 ppm frequency accuracy. The VCTCXO–module requires
about 4 ms to settle into final frequency. Amplitude rises into full swing in
about 3 ms, but because frequency settling time is higher, this oscillator
must be powered up early enough.
