GAIM (PMB 2905) is a A/D converter chip that converts IQ signal into digital format
and also creates analog transmitter signal for radio module. GAIM also converts the
signals from mic and signal to erp.
Battery and temperature measurements but also the PA control is handled by GAIM.
HIGOLD (PMB 2800(SP PMB2707 and uC PMB2706)) is the main IC that could be
handled as two different parts SP and uC. uC includes 80C166 CPU, channel coding
functions, digital controls, GSM specific timers, DSP controls, SIM interface and MMI
