Patent ID: 7920836

Claim:
A portable transceiver having a system for saturation detection, correction and recovery in a power amplifier, comprising: a transmitter coupled to a receiver; a power amplifier located in the transmitter; a closed power control loop configured to develop a power control signal (V PC ); and power control circuitry configured to reduce the power control signal if the power amplifier is operating in a saturation mode, the power control circuitry further including: a comparator configured to receive the power control signal and a reference signal and develop a logic high signal if the power control signal exceeds the reference signal; and a switch, a current source and a capacitance at the output of the comparator, the switch configured to close when the output of the comparator is logic high, the current source configured to charge the capacitance when the switch is closed, the current supplied from the current source being subtracted from the power control signal.
