Abstract

A simple meter of integral values of the reflection coefficient magnitude in the microwave frequency band and a wide frequency band using a low-intensity noise signal is described. Its principle of operation is based on one of the modifications of the null measurement methods. On the one hand, the application of this principle increased the measurement accuracy and, on the other hand, significantly simplified the design of the meter and implemented it as a portable device. The integral error of the nonlinearity of the transfer characteristic in absolute values of the reflection coefficient magnitude did not exceed 0.003 with a measurement resolution of 0.001.
