A Dual Six-Port Automatic Network Analyzer

Abstract

A 2- to 18-GHz dual six-port automatic network analyzer using diode power detectors is described. An analysis of the calibration technique is discussed in detail. Measurement accuracies of better than 0.1-dB up to 40-dB insertion loss from 2 to 7 GHz are reported. Possible causes of the errors observed at higher frequencies are given.
