A Dual Six-port Automatic Network Analyzer And Its Performance (Short Papers)

A computer-controlled six-port automatic network analyzer (ANA) capable of measuring complex reflection coefficients of one-port devices, effective efficiencies of power sensors, and S-parameters of two-port devices over 2-18 GHz is described. System calibration based on the TRL technique is discussed and performance tests on measuring effective efficiencies, reflection coefficients, and S-parameters are summarized.
