Patent ID: 8351880

Claim:
A radio frequency (RF) power amplifier (PA) module having a saturation corrected integration loop comprising: saturation detection and correction circuitry adapted to: receive an input ramp signal, which is indicative of a desired PA output voltage; detect saturation of PA circuitry based on a difference between the desired PA output voltage and a detected PA output voltage; and provide a saturation corrected input ramp signal (SCIRS), such that when saturation of the PA circuitry is not detected, the SCIRS is indicative of the desired PA output voltage and when saturation of the PA circuitry is detected, the SCIRS is held to approximately a constant value during a duration of each of a plurality of data transmit bursts; an integrator adapted to receive and integrate a detector output signal based on a setpoint established by the SCIRS to provide an integrator output signal; the PA circuitry adapted to: receive and amplify an RF input signal to provide an RF output signal having a PA output voltage; transmit the plurality of data transmit bursts using the RF output signal; and in preparation for each data transmit burst, ramp up the PA output voltage in response to the integrator output signal; and detector circuitry adapted to detect the PA output voltage to provide the detector output signal, which is indicative of the detected PA output voltage, wherein when saturation of the PA circuitry is not detected, the saturation corrected integration loop is adapted to regulate an output power from the PA circuitry based on the desired PA output voltage.
