Abstract
Methods and systems for operating a transceiver are described. A transceiver can include an upconverting mixer, a downconverting mixer, a controller, and an envelope detector. The upconverting mixer can mix an input signal with a local oscillator (LO) signal to generate a transmitter signal. The envelope detector can receive the transmitter signal outputted from the upconverting mixer and output an envelope of the transmitter signal to an output line of the downconverting mixer. The envelope can indicate at least one of a leaked LO signal and an image signal. The controller can receive a calibration parameter that is based on at least one of the leaked LO signal and image signal and calibrate the upconverting mixer based on the calibration parameter.
