Two-channel acousto-optic modulator (AOM) makes simultaneous assignment of the frequency and phase of radio-signals possible. AOM is a fundamental element of a spectrum analyser based on acousto-optic receiver. In the paper, an analysis of influence of structural elements on characteristics of a two-channel modulator was shown and the procedure of optimisation of its construction described. Basing on this procedure the modulator for spectrum analysis at GSM band was designed, performed and investigated. The two-channel acousto-optic modulators give the possibility of detection and defining direction of radiation with accurancy of optimisation of construction of two-channel acousto-optic modulator for radio-signal phase detection 0,5⁰ .
