6E-4Transmitter3.0 Transmitter3.1 General(Refer to Figure 6-1) The Lowband transmitter consists of the following basic circuits: 1.power amplifier (PA) 2.antenna switch 3.harmonic filter 4.antenna matching network 5.power control integrated circuit (PCIC).3.1.1 Power AmplifierThe power amplifier consists of two LDMOS devices: 1.PA driver, U101 and 2.PA final stage, Q100. The LDMOS driver (U101) provides 2-stage amplification using a supply voltage of 7.3V. The amplifier is capable of supplying an output power of 0.3W (pins 6 and 7) with an input signal of 2mW at (pin16). The current drain is typically 120mA while operating in the frequency range of 29.7 - 50 MHz. The power output of this stage is varied by the power control loop which controls the voltage on pin 1. The LDMOS PA is capable of supplying an output power of 8W with an input signal of 0.3W. The current drain is typically 2000 mA while operating in the frequency range of 29.7 - 50 MHz. The final stage gate is bias by a voltage from PCIC pin 24. This voltage is the output of a programmable DAC inside the PCIC and the output is adjustable with the radio tuner.Figure 6-1: Lowband Transmitter Block DiagramPCIC PA PA F i n a l Antenna Switch/ Driver Sta ge Harmonic FilterVcontrolGate biasFromAntenna Matching NetworkPower Amplifier (PA) VCOAntenna switch bias SPI bus
