Claim 13:
14. A method comprising:
generating a first oscillator signal at a predetermined frequency using one or more phase-locked loops of a down converter;
generating a second oscillator signal that is a multiple of the first oscillator signal using a frequency multiplier of the down converter;
receiving a radiofrequency signal at an input of the down converter;
filtering the radiofrequency signal using a waveguide roofing filter of the down converter;
mixing the filtered radiofrequency signal with the second oscillator signal using a frequency mixer of the down converter;
compensating for temperature-induced changes in gain using one or more temperature compensation elements to signals generated of the frequency mixer;
filtering output of the frequency mixer using a bandpass filter of the down converter and a low pass filter of the down converter to generate an intermediate frequency signal; and
outputting the intermediate frequency signal as an output of the down converter.
