Abstract
A calibration circuit for calibrating harmonics in a mixer. The calibration circuit includes an RF signal path configured to receive an RF signal corresponding to an output of the mixer, selectively receive a test signal injected into the RF signal path, and provide feedback to the mixer according to the RF signal and/or the test signal. The test signal corresponds to a selected harmonic of the harmonics in the mixer. A measurement circuit is configured to detect, in the output of the mixer, the test signal injected into the RF signal path. A calibration module is configured to receive a feedback signal indicative of the test signal detected in the output of the mixer and, based on the feedback signal indicative of the test signal detected in the output of the mixer, adjust a duty cycle associated with the mixer to calibrate the selected harmonic.
