Abstract

Special interest in the region of measuring technique of MM and subMM wavelength bands consists in carrying out devices for rapid frequency measuring and estimating of harmonical UHF signals intensity in wide frequency band 60-600 GHz. Power minimum level of these signals is equal 106 -iO W and its dynamicd range of input levels is equal about 60 dB. The measuring thne provided by this technique is equal not more 1 sec. In a number of works [1-3] of the recent time physics and technical bases and applied aspects of the Josephson effect concerned to problem of electromagnetic UHF radiation frequency measuring is examined. In these works a mechanism of the Josephson junction interaction with external electromagnetic UHF signals and relations, are given which simply connect the frequency of its oscillation with the voltage on the Josephson junction. The procedure of the harmonica! signal frequency measuring functionally may be reduced to the estimating of "special features" of the volt-ampere characteristic (VAC) or inverted VAC of the Josephson junction, which displays in the form of a step break of the characteristics under the strict coincidence of the external UHF frequencies and own oscillations of the junction under non-stationary mode as a result of its interaction. Thus for measuring harmonical and poliharmonical signals on the basis of the non-stationary Josefson effect it is necessary to identify the special feature of the VAC or *VAC and their deflection and to determine coordinates of the central point of the special feature or the *VAC deflections asymmetry center.
