GENERAL DESCRIPTIONS
2.1 Multi-band :
CMD-MZ5 support E-GSM 900 and DCS 1800 multi-band functionality.
Because the usage of multi-band depends on network capabilities, the phone is able to operate as a single band
mobile in GSM 900 as well as in DCS 1800; In addition, it supports the extra functionality required for multi-band
mobile stations: Inter-band/“seamless” hand-over, channel assignment, cell selection and re-selection, all between
both bands within a Public Land Mobile Network.
The manual and automatic PLMN selection in both bands is given.
The user does not need any special action to use the multi-band functionality of the phone.
Users are able to manually roam between PLMN’s operating in GSM 900 and DCS 1800 bands.
The CMD-MZ5 is a phase II, GSM 900 class 4, DCS 1800 class 1 mobile phone.
The nominal maximum output power for GSM 900 is 2W, for DCS 1800 1W.
2.2 Real Time Clock (RTC)
The real time clock is integrated into phone.
When the mobile is switched on the RTC is powered via the CPP.
When the phone is powered down, the RTC is powered from the main battery via its own low quiescent current
regulator.
When the main battery is low or removed, a back-up battery keeps the clock alive.
2.3 Vibra Alert Functionality
The vibrator is a 1.3V device.
A general port pin of the SC1 controls the switch mode of the vibration motor. It is powered through a regulator by
an interface control unit. If the mobile is in the phase of switching on or off the vibrator is off at all times.
2.4 Battery Safety
The battery pack contains a safety circuitry. The charging circuitry and the safety circuitry together guarantee a
double fail-safe battery pack. This means that each component can be either short or open and still all the safety
requirements will not be violated.
The safety concept protects against:
Over voltage
when Vbat falls below 4.06V - 4.15V.
Under voltage
Charging is still possible.
: The charging is stopped when Battery Voltage (Vbat) reaches 4.24V- 4.3V. The charging resumes
: When the cell voltage drops below 2.5V - 2.7V the cell is disconnected for discharging.

7.1.2 Operational Description
(1) Receiver Section
Radio signals received from the antenna located on the top of cabinet enter the RF connector of common
connector (CN401) provided at the bottom of cabinet.
After they are separated from the signals coming from external units by a mechanical switch, they enter the
antenna switch module (CP702). This module separates the signals transmitted/received to/from the antenna by
means of the switch, and also selects GSM or DCS band. The received signals are separated here into GSM side
and DCS side.
The received signals in the GSM band pass through the band-pass filter (SWF702) from CP702 to remove the
signals out of the receiving band. Then, the received signals are amplified in the low-noise amplifier using the
transistor (Q702).
Further, the band-pass filter (SWF704) removes unnecessary signals out of the band.
The SWF704 output signals are balanced signals. Thus, the signals from band-pass filter can be entered as
balanced signals to the subsequent RF IC CXA3200ER (IC604) having a balanced input system.
Similarly, the received signals in the DCS band pass through the band-pass filter (FL701) from CP702 to remove
the signals out of the receiving band. Then, the received signals are amplified in the low-noise amplifier using the
transistor (Q701), and further the band-pass filter (SWF703) removes unnecessary signals out of the band. Same
as in GSM band, the SWF703 output signals are also balanced signals, so that they can be entered to the IC604
as they are. FL701 is a dielectric filter, while SWF702 to SWF704 are all SAW filters.
To prevent characteristic deterioration due to bias point fluctuation at high temperature, the Q701 and Q702
detect current flowing in the transistors using signals at pins 37 to 39 of IC604 and perform the feedback control
so that the current flowing in the transistors is constant at all times.
Respective input signals in GSM and DCS bands entered to the IC604 are entered to the receiving mixer in the
IC604. They are mixed with local signals from VCO601 in the mixer and converted into IF signals in the 440MHz
band. The output of IF signals passes through the band-pass filter (SWF601) where unnecessary signals are
removed. The SWF601 output signals return to the IC604 again.
The SWF601 input/output signals are all balanced signals. The signals in the 440MHz band that returned to the
IC604 are adjusted to proper level signals by variable gain amplifier (PGC) in the IC604, and then they are
orthogonal-demodulated with 440MHz signal obtained by dividing the oscillation frequency 880MHz by two at the
signal reception from VCO602, and they become base band IQ signals in the IC604.
The received signals that became base band IQ signals pass through low-pass filter in the IC604 to remove
unnecessary signals, and then they are sent to the base band side.
The signals sent to the base band side are IQ signals having 1.4V DC offset.
(2) Transmitter Section
IQ signals transmitted from base band side are modulated into signals in the transmission IF frequency band by
an orthogonal modulator in the IC604. IQ signals must have DC offset voltage 1.575V typ. and signal amplitude
500mVp-p. The transmission IF frequency is 195MHz (975MHz/5) when the terminal is in GSM mode, or 325MHz
(975MHz/3) in DCS mode. By this modulation, local signals are generated by dividing the oscillation frequency
(975MHz) by an internal frequency divider (3/5 switching) at the signal transmission from VCO602.
The modulated signals outputted from orthogonal modulator pass through low-pass filter in the IC604, and then
they enter the phase comparator of the offset loop system modulator.
In the offset loop system modulation, the VCO having same oscillation frequency as transmission frequency is
assembled in the phase lock loop, and the reference frequency of this phase lock loop is used as transmission IF
frequency to adjust the phase shift of VCO to that of transmission IF frequency. As a result, the same effect as if
the phase modulation was applied to the transmission frequency can be attained.
Also, the transmission frequency can be selected simultaneously by using the output of VCO mixed down with the
frequency divided by VCO601 as a comparison frequency of the phase lock loop.
Unlike conventional mix up system, this offset loop system can reduce spurious signals generated in the mixer.
The output signals of offset loop are converted into the GMSK modulated signals by the power VCO, VCO801.
This VCO has two outputs of GSM band and DCS band, and the operation modes can be switched by signal lines.
The output of VCO801 is already GMSK modulated waves of transmission frequency. The output of VCO801 in
the GSM band passes through the low-pass filter FL805 where harmonic component is attenuated. As the PA
module CP803 has only one input, this output is composed into one in the diplexer FL806. Also, a part of signals
returns to the IC604 for the input of phase lock loop. The output of FL806 enters the PA module CP803 via the
matching circuit. The CP803 is a power amplifier having dual bands, and which frequency is to be outputted is
switched over by the signal lines.
This power amplifier has output controllable terminals, so that the output voltage can be controlled according to
external voltage.
The CP803 generates two outputs, GSM and DCS.
27
Page 28
These two outputs pass through low-pass filters CP801 and 802 respectively to remove harmonic component.
These CP801 and 802 are also used as directional couplers to detect a part of the power amplifier output for the
power control. The outputs of CP801 and 802 are entered to the front-end module CP702. This module switches
over the transmission, reception, and band, as mentioned previously. The signals entered to the CP702 are
outputted from the antenna via reversed route of received signals.
The signals detected in the CP801 and 802 are entered to the D803 and D802 respectively, and they are rectified
to become DC voltage components. These outputs are composed into one, and it is compared with APC signal
from base band in the operation amplifier IC801 to be the signal to control the CP803 so that the output voltage
can follow the APC signal.
(3) PLL Section
The PLL block consists of dual PLL (IC601) and VCO601 and VCO602. The VCO601 is for channel PLL and
generates thefollowing oscillation frequencies.
GSM band
The output of VCO601 is entered to the FL601 and distributed to two outputs. One of these outputs returns to the
IC601, and another output is entered to the IC604. In the transmission of GSM band, the signal entered to the
IC604 is divided into two internally, and therefore the frequencies of every 400kHz step are used in this case only.
The VCO602 is for local PLL and generates the following oscillation frequencies.
Transmission : 975MHz
Reception : 880MHz
At the signal transmission, 975MHz is divided into five in the GSM band, or three in the DCS band in the IC604.
At the signal reception, 880MHz is always divided into two in the IC604.
