Abstract

Single-function microwave frequency detectors are used in the structures of multichannel frequency discriminators. They allow determining the frequency of an unknown signal in a very short time of the order of hundreds of nanoseconds. The shape of the output voltage of the single-function detector versus frequency is described with a cosine or a sine function. In the systems, where a great accuracy of frequency determination is not required, and a time measurement is vital, it is possible to apply only one single-function frequency detector. A single-function frequency detector is composed of two blocks: a system of developing of proportional phase difference and a phase sensitive detector. The function of the first block is to generate two output microwave signals with a phase difference between them proportional to the frequency of the input signal. A phase sensitive detector converts the difference of phases of input signals into voltage. The output voltage is subject to further processing and, based on it, the frequency of the input signal is determined.
