Abstract
A transmitter includes a power amplifier coupled to amplify an input signal and provide an output signal. A radio frequency coupler is coupled to receive the output signal and provide a measured signal on a coupler output. A measurement receiver multiplexor is coupled to receive the measured signal on the coupler output to produce either a non-phase adjusted signal or a phase adjusted signal on one of a plurality of multiplexor outputs. Multiple receiver paths are coupled to the plurality of multiplexor outputs to receive either the non-phase adjusted signal or the phase adjusted signal. Receive path processing circuitry is configured to produce in-phase and quadrature phase digital signals based on the plurality of multiplexor outputs to digital processing circuitry to cancel 3or 3and 5order measurement receiver distortions.
