Abstract
An intermediate frequency receiver includes mixers for generating first and second IF signals from a RF signal and local oscillator signals. A magnitude calibration loop adjusts a gain of the first and/or second IF signals generated from the mixers depending on a magnitude difference between the IF signals. The phase calibration loop adjusts a phase of a local oscillator signal before being used at the mixers depending on a phase difference between the IF signals.
