Abstract
A RFPA (radio frequency power amplifier) circuit () which includes a RFPA (), a supply voltage source (), means () for applying to the RFPA a gain control bias voltage and a feedback control loop () for adjusting a voltage applied to the RFPA, the feedback control loop including a sampler () for sampling an output of the RFPA, a RF detector () for detecting a level of RF power sampled by the sampler, a comparator () for comparing an output signal from the RF detector with a reference signal, an integrator () for integrating an output signal of the comparator and a voltage regulator () having a first input from the integrator and a second input from the supply voltage source and an output connected to the RFPA, the regulator being operable to apply to the RFPA a supply voltage adjusted in response to an input signal from the integrator.
