It would then be amplified and applied to the final rf power amplifier. The size of the rf modules is very small and have an extensive range of a operating voltage that is 3v to 12v. Theoretically every audio amplifier produces some amount of power amplification but in practical scenario every audio amplifier cannot be called a power amplifier.

The transmit receive or transceiver section the baseband signal processor the power amplifier and the power management subsystem.

The one displayed is based on a cellular phone. This module will review the transmit receive block and the power amplifier in detail. The carrier path is always amplifying the input signal and produces output power over a wide range of input powers. It would then be amplified and applied to the final rf power amplifier.
