A network analyzer for making accurate measurements in the 75-110-GHz band is presented. The analyzer operates by sampling forward and reverse signals using back-to-back directional couplers. The tapped signals are combined in a hybrid coupler which feeds the sum and difference into two detector diodes. An additional two measurements are obtained by switching a phase delay into one of the paths. These four measurements are manipulated using six-port theory to calculate the complex reflection coefficient. A 27-40-GHz prototype operating as a reflectometer is demonstrated. Calibrations and measurements are performed interactively with the aid of a Macintosh II personal computer equipped with a high-resolution color display.<>
