14. MOD The P A Circuit and its control The power amplifier control circuit ensures that the RF signal is regulated to the required limits of operation The TX RF signal is input on 1 1 106 or IC107 and the power amplifier outputs the signal at 4 IC105 and IC108 are op amps which output a control signal to the Power control is carried out by measuring the current drawn by the P A see Fig 9 P A Circuit Control The current drawn by the P A is directly proportional to the output power and is measured as a voltage drop across a known resistance path or Fixed Control Loop Stripline This consists of a 47mOhm resistor R144 for GSM or two resistors in series a 47mOhm R144 and 27mOhm R136 for PCN The voltage drop V ERROR is then integrated by the operational amplifier IC108 to give an error voltage which regulates the TXP signal The TXP input signal to the power control circuit is generated by the IC27 90 TXP provides a limit for the frequency spectrum caused by burst modulation lt gt The signals 3V_P_TX and 3V_G_TX are controls supplies used to enable the two power control op amps IC105 and IC108 The output from the P A follows the TX path which uses the control supplies GSM_PRE_ON or PCN_PRE_ON to enable the TX switching diodes D400 D401 The RF signal then passes through the diplexor and onto the antenna The diplexor is tuned to the GSM or PCN duplex spacing so enabling se

27. If the alarm wake up has been set by the user and it activates then an interrupt is generated internal to NELL and the HHP initiates its power up routine When an interrupt is detected by NELL from one of the aforementioned inputs then the ILB circuit will commence its power up routine The ILB will firstly output a high voltage on HARD PWR P2 this is then fed to the input EN2 28 on MiniMoe which in turn activates regulator 2 internally and this then powers up the 3VNELL line The flash PROM and EEPROM will now power up The HARD PWR signal also activates the power supply MicrMoe 204 which supplies the outputs 2V8 RF1 2V8 RF2 2V8 to sections of the RF circuitry The ILB then sets the RG3VPWR NELL H1 line high which enables regulator s 3 and 7 internally within MinMoe EN3 21 Both the 3VSC and 3VAUDIO lines are now activated and so power up the CSP DSP SRAM IC9 and Audio Once the main control devices are active the ILB enables 5VRFON 19 and SIMPWR 20 to power up the 5VRF and SIMVCC lines When the power key is pressed the interrupt is detected by KEY1 H1 on NELL which outputs a low voltage onto the HARD PWR RG3VPWRN 5VORFON and SIMPWR control lines This in turn switches off the regulator s 2 3 5 6 7 and MicroMoe IC204 thus powering down the HHP The power down sequence is done in stages so as to ensure that all data and control operations are accomplished in order and t
