Abstract
A system includes a radio frequency (RF) signal path configured to receive an input signal that includes at least one of a test signal and an RF signal. A local oscillator (LO) signal path is configured to supply a LO signal. A mixer includes a first input in communication with the RF signal path and a second input in communication with the LO signal path. A calibration control module is configured to receive an output of the mixer in response to the test signal and to adjust an effective duty cycle of the LO signal in the LO signal path based on the output of the mixer.
