The Circuit and Network Analysis of Some Signal Separation Structures Constituting Microwave Six-Port Reflectometers

摘要

The circuit and network analysis of some signal separation structures constituting a microwave six-port reflectometer are presented. An interconnection of five of these structures composing a six-port network analyzer is also presented. In order to validate the responses, a circuit analysis following the signals from source to detectors, is performed. The complete structure constituting the six-port network analyzer is composed by a 6 dB directional coupler, a four stage 3 dB Wilkinson power divider and three quadrature couplers providing 3 dB, which are formed by two 8.34 dB tandem couplers.
