Abstract
We describe a quasi-optical diplexer for the two-channel receiver of an RT-7.5 radiotelescope of the N. É. Bauman Moscow State Technical University. The issues of design of frequency-selective surfaces and methods for measuring their frequency characteristics are discussed. Diagrams of the quasi-optical diplexer and the measuring bench are given along with the frequency characteristics of manufactured frequency-selective surfaces.
