Abstract

For the purpose of studying the microwave parameters of the thermonuclear plasma, radioastronomic applications, etc., wide-band high-sensitive high-speed spectrum analyzers, radiometers, and receivers are required which operate in the frequency range of 50 - 300 GHz and higher. The existing techniques have a number of disadvantages. Thus, the high-speed heterodyne receivers are rather narrow-band ones, therefore, to cover the whole millimeter- wave band, complex multichannel systems should be designed. On the other hand, the wide- band Fourier spectrometers are very inertial and complex systems and have great losses in the long-wave portion of the millimeter-wave band.
