Abstract

A unique noise measurement system for simultaneous determination of the impedance and noise temperature of microwave one-ports is presented. It employs a multi-state total-power radiometer, and techniques of calibration and error correction. Good measurement accuracy has been achieved using a high precision radiometer fitted with a noise injecting circuit to excite the DUT.
