Radio-photon mixer of microwave radio signals: theoretical description and experimental study

Blog Article

In this paper, a theoretical calculation of a radio-photon mixer is performed using spectral analysis of signals and the results of an experimental study of the spectral composition of optical signals in a radio-photon mixer.An experimental setup consisting of a source of optical radiation, two Mach - Zehnder modulators, an optical spectrum analyzer and auxiliary equipment for specifying the bias voltages gtech brush bar and the formation of microwave signals is presented.Expressions are obtained for determining the amplitude coefficients of the harmonic components in the spectrum of the signal of the radio-photon mixer at the output of the second electro-optical modulator.As a result of the cartoon martian with big head experimental study, the amplitudes of the combination components in the optical spectrum at the output of the mixer under study were determined.
