Search for: [Description = "We present a new four\-state interferometer for measuring vectorial reflection coefficient from 50 to 1800 MHz. The interferometer is composed of a four\-state phase shifter, a double\-directional coupler and a spectrum analyzer with an in\-built tracking generator. We describe a design of the interferometer and methods developed for its calibration and de\-embedding the measurements. Experimental data verify good accuracy of the impedance measurement."]
