description A radio frequency (RF) transceiver includes an RF receiver having an RF receiver path that processes a received signal to generate inbound data, the receiver path having an RF front-end. A power amplifier calibration module generates power amplifier calibration signals in a calibration mode of operation, and generates power amplifier pre-distortion parameters in response to a calibration feedback signal. An RF transmitter processes output data to generate a transmit signal based on the power amplifier pre-distortion parameters in a transmit mode of operation and processes the power amplifier calibration signals to generate an amplified calibration output in the calibration mode of operation. A power amplifier calibration feedback path generates the calibration feedback signal, separate from the RF front-end, in response to the amplified calibration output.
