ABSTRACT:
A radio transmitter includes a power control table, a power amplifier, and a power controller. The power control table includes a plurality of control values. The power amplifier amplifies an RF signal for transmission with an adjustable gain. The power controller adjusts the gain of the power amplifier based on the power control table and a temperature signal that is indicative of a temperature of at least a portion of the radio transmitter.
