Abstract:
A method and system for linearizing a Radio Frequency Power Amplifier (RFPA) is disclosed. The method comprises calibrating signals in the RFPA to linearize the RFPA, using at least one of a first signal, a second signal, a third signal, and a fourth signal. The first signal is generated corresponding to ambient temperature. The second signal is generated corresponding to process corner of transistors in the RFPA. The third signal is generated corresponding to power supply voltage. The fourth signal is generated by feeding back output of the RFPA.
