Polar transmitter calibration Various embodiments relate to a transmit and receive system using polar modulation, including: a transmitter configured to produce a transmit signal using modulation; a receiver configured to receive a transmit signal using in-phase/quadrature (IQ) processing; a Tx/Rx switch configured to loop a transmitted signal from the transmitter back to the receiver for calibration; and a controller configured to: command the transmitter to generate a real signal; command the Tx/Rx switch to loop the real signal back to the receiver to produce a first received signal; command the transmitter to generate an imaginary signal; command the Tx/Rx switch to loop the imaginary signal back to the receiver to produce a second received signal; determine a compensation parameter based on the first received signal and the second received signal; and command the receiver to compensate a third received signal based upon the compensation parameter.
