Abstract
A system can include an input signal source, a local oscillator (LO), and an intermediate frequency (IF) receiver to receive an input signal from the input signal source and an LO signal from the LO. The IF receiver can include a switch to switch between the first and second inputs to provide an output. The IF receiver can generate a calibration signal from the LO signal.
