Title :
A broadband radiometer for calibrating mismatched noise sources

Abstract :
The accurate modeling of the effect of source match on receiver noise is reported. This makes it possible for mismatched noise sources to be calibrated accurately with neither isolators nor tuners. The broadband radiometer used for the calibration is briefly described.<>
