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. Mitsubishi Electric Telecom Europe SA ZA le Piquet, 35370 Etrelles Phone: +33 2 99 75 71 00 Fax: + 33 2 99 75 71 47 Version E Date: 04/00

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.

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: 0% 40% 80% 1 bar 97% 100%
3 bars
2 bars
0 bar
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 Battery level 3.86V 3.71V 3.57V 3.46V Call Mode Battery level 3.77V 3.60V 3.40V 3.30V
Initial thresholds 3 bars 2 bars 2 bars 1 bars 1 bar low battery alarm Power off
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.
When battery voltage is less than the threshold given in the table above, BAT_EMPTY is true. Version E Mitsubishi Electric Telecom Europe SA Date: 04/00 ZA le Piquet 35370 Etrelles Phone: +33 2 99 75 71 00 Fax: + 33 2 99 75 71 47

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.

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.

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.

For RSSI ADJUSTMENT, we choose : RF menu, Adjustment, Adjustment RX, Adjustment RSSI (rapport AGC).
Then we get the RSSI window :
To adjust RSSI ,we input a GMSK modulated signal (67.7 kHz shifted) at level and channel as follow : Step 1 2 3 4 5 6 7 8 Channel 37 37 525 525 695 695 868 868 Level (dBm) -82.5 -31.5 -82.5 -31.5 -82.5 -31.5 -82.5 -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).
