2.2 Description.

The battery is NiMH 900mAh, 3.8 V nominal for Galaxy, Astral and Geo
External power supply for charging (EXPS) comes from the DC jack at the bottom side of the mobile

(AC/DC, CLA, DTC or H/F Kit). This power supply is 5.8 V nominal. Battery presence and battery
type information are accessible in CHGM IPD register. If a Li-ion battery is detect, the software
considers that the battery is absent.

The battery temperature information (TH) is given by thresholds in IPD CHGM register. This
information are used only for charge control.

The battery level information is accessible in an A/D converter in One-C. It is also available in CHGM
IPD register , these information are given by range only for range control.

External power supply (EXPS) presence information are accessible in CHGD IPD register. As
described in the drawing above, the power supply for Base Band (IC300) comes from EXPS when it is
present because EXPS level (5.8 V) is always greater than battery voltage. On the contrary, power
supply for radio always comes from the battery.

The serial diode between battery and One-C (IC300) can be bypassed by software to reduce voltage
headroom. Bypass is Activated when battery is less than 3.45 V.

2.3 Charging process.

Charging process follows these successive phases :

Pre charge :This phase is mandatory before the rapid charge to verify that battery operation is
normal (normal battery voltage and temperature). Charge current during this phase is 52 mA. If the
battery voltage is higher than 3.3 Volts, the S/W launch IPD charger in rapid charge except if the
temperature is not between 0°C and 55°C.

2) Rapid charge : Charge current during this phase is 420mA. If battery temperature becomes
abnormal IPD charger start at low current charge (21 mA), while temperature comes back normal
(between 0°C and +55°C) during 15 mn. Full charge detection ends Rapid charge. Full charge is
detected by S/W when charge current decreases under 50 mA (full charge convergence current).

3) Trickle mode :This phase is necessary to complete the charge and to avoid battery auto
discharge. Charge current during this phase is 21 mA. Trickle charge is automatically stopped after 24
hours duration.

2.4 Main characteristics.

The phone transmits only if the battery is attached to it, in any configuration of power supply. When
the phone is connected to H/F adapter, DTC, AC/DC, or CLA, the battery charging circuit operates.
Battery voltage (+3.8 V) is applied via D118 or from TESTPS ( J103 pin1 ) through D124 when using
Hand Free.
The main power supply is fed to the phone either from the attached battery via the connector J101, or
from accessories :

• H/F adapter,

• Desk Top Charger DTC,

• AC/DC adapter and CLA via the external connector J103.

R120 and R121 give an internal voltage reference. If the battery voltage VBAT falls down, then
BYPASS shorts out the diode D118 through TR103 to reduce voltage drop.

2.5 Autonomy Control.

The battery energy is displayed on the LCD by a 3 bars “battery icon” . Voltage thresholds for each
bars are calculated to have this autonomy time share out:

1 bar

97%

0 bar

40%

3 bars

A 3 times 33% time shares out is not possible because of the very stable battery level between 20%
to 50% autonomy time. In addition with these bars, a ” low battery alarm” is displayed between ”1
bar” and the mobile off.

All these thresholds are programmed in EEprom by the factory and given in following thresholds
table.

Idle Mode Call Mode
Initial thresholds Battery level Battery level
3 bars → 2 bars
2 bars → 1 bars
1 bar → low battery alarm
Power off 3.46V 3.30V

Thresholds are different according to the mode, Idle mode or Call mode. Idle mode threshold are
checked by software 25 min after the end of the call.

3.86V 3.77V

3.71V 3.60V

3.57V 3.40V

2 bars

80%

When battery voltage is less than the threshold given in the table above, BAT_EMPTY is true.

Incoming RF signal from aerial is filtered and switched to the RX GSM path through SW700 . The
signal is filtered by FL504 , before to be amplified by TR504 , and is further filtered by FL503. Then,
the signal input to RF-IC (IC600) in a first mixer stage. The RF signal (925-960 MHz) is mixed with
the RF-PLL Frequency (1150-1185 MHz) coming from IC601 (PLL) via IC602 (RF-VCO). For the
channel 1, the output signal of the mixer is 225 MHz (1150 MHz-925 MHz =225 MHz), and is filtered
by FL500.

DSC band (1805-1880MHz).

Incoming RF signal from aerial is filtered and is switched to the RX DCS path through SW700 . The
signal is filtered by FL501 , before to be amplified by TR503 , and is further filtered by FL502. Then,
the signal input to RF-IC (IC600) in a first mixer stage. The RF signal (1805-1880 MHz) is mixed with

3.5 Transmission.

3.5.1 Transmission Block Diagram.

3.5.2 Description of Transmission Block Diagram.

The direct and phase shifted signals are then fed to I and Q modulators inside the IC600. I and Q data
components are fed into the IC600. The output from the two modulators is summed and fed out of
pin 11. The GMSK signal leaves the modulator of IC600, and is amplified also inside IC600.

E-GSM Band (880-915MHz).

A phase locked loop is created around the TXVCO IC700. The output is fed into IC600 and converted
to 270 MHz (135MHz on DCS) by mixing with RFVCO at 1150-1185 MHz (1575 – 1650 MHz DCS).
This 270 MHz signal is compared with the 270MHz signal from the modulators, and the error signal is
used to control the TXVCO. Note that the error signal on TP700 will have a DC component to control
frequency, and an AC component at approx 270 kHz to control phase changes. Then the signal is
filtered, amplified by TR702, and further filtered before to input to the power amplifier (IC702).From
the PA, the output goes through coupler Z701, is switched to the TX path and is filtered by SW700.
The signal then goes up to the antenna.

DCS Band (1710-1785MHz).

A phase locked loop is created around the TXVCO IC700. The output is fed into IC600 and converted
to 135 MHz (270 MHz on GSM) by mixing with RFVCO at 1575 – 1650 MHz. This 135 MHz signal is
compared with the 135MHz signal from the modulators, and the error signal is used to control the
TXVCO. Note that the error signal on TP700 will have a DC component to control frequency, and an
AC component at approx 270 kHz to control phase changes. Then the signal is filtered, amplified by
TR712, and further filtered before to input to the power amplifier (IC702).From the PA, the output
goes through coupler Z 700, is switched to the TX path and is filtered by SW700. The signal then
goes up to the antenna.

4. Speech coder.

Audio is sampled at 8 kHz rate, and divided into 20 ms blocks of 160 samples per block. Each 20 ms
block is characterised by 260 bits i.e. 13 kbits/sec. The resulting signal is processed by a regular
pulse excitation - long term predictor (RPE - LTP) codec. This yields a digital representation of vocal
chord vibrations, together with the filter characteristics which must be applied to them to make voice
sounds.
The most significant 182 bits will go through error correction and become 378 bits. The less critical
group of 78 bits will not go through error correction and will just be summed with the 378 bits which
will yield 456 bits.

These 456 bits are then separated in 8 blocks of 57 data bits.
These blocks are interleaved with adjacent blocks to guard against burst errors and broken up into
blocks of 114 bits for transmission. This block of 114 bits are the data bits of the timeslot.

Timing data is added, and the resulting bit stream is fed to the Gaussian Minimum Shift Keying
(GMSK) modulator, where the bits are taken two at a time and used to smoothly change the phase of
an RF carrier according to bit combination.

4.1 Full rate / Half rate / Enhanced full rate.

The data rate of 13 kbit/sec ( full rate ) is considerably lower than for direct speech digitising as in
PCM. Now more advanced voice coders cut this to 5.6 kbit/sec ( half rate coding ).
The enhanced full rate, is just a full rate with a different speech coder which improves the
transmission quality.

To adjust RSSI (if RX level is not good, for example), you have to process to different steps :
RX SPLIT and RSSI ADJUSTMENT

• For RX Split we choose :

RF menu, Adjustment, Adjustment RX, Split RX as follow :

Then we fix RX split at the right value :
For the E-GSM band the number of sub-bands is 1(no split)
For the DCS band the number of sub-bands is 3
We split the DCS band as follow : L range : 512 to 539

M range : 540 to 850
H range : 851 to 885

The RX split window should be as follow :

Now you can adjust RSSI for each sub-band.

Then we get the RSSI window :

Level 3 Service Manual

To adjust RSSI ,we input a GMSK modulated signal (67.7 kHz shifted) at level and channel as follow :

Step Channel Level (dBm)

1 37 -82.5
2 37 -31.5
3 525 -82.5
4 525 -31.5
5 695 -82.5
6 695 -31.5
7 868 -82.5
8 868 -31.5

If the RX level measurement is not good in E-GSM we adjust only the E-GSM band (step 1 and 2)
If the RX level measurement is not good in DCS we adjust only the DCS band (step 3 to 8).

7. Basic Adjustment.

7.1 Power Adjustment.

For the M4 Family Mobiles, Mitsubishi uses only MELCO HPA (IC701). Each mobile is adjusted in the
factory and the TX parameters (Power Control Level values and ramping values) are stored in the
EEPROM (IC202).

About the adjustment value of TX Power, see the following table.
