FIELD: information technology. ^ SUBSTANCE: circuit consists of power amplifiers, receiving amplifiers, at least one splitter, at least one combiner, a duplexer and frequency and/or band-pass filters, high-frequency switches and a detector circuit for detecting transmission signals from a transceiver and for switching the high-frequency switches to the required state. The circuit comprises universal input module with high-frequency switches on the antenna of signal transmission channels, a broadband receiving amplifier and at least one splitter which distributes the output signal of the receiving amplifier to several outputs of the input module, as well as a universal output module with high-frequency switches for switching signal transmission channels, connected to the transceiver via the detector circuit, as well as at least one receiving amplifier and at least one combiner, bringing together the input signals of several inputs of the output module. The input and the output modules can be combined and connected differently with various power amplifiers and different frequency and/or band-pass filters. ^ EFFECT: designing a circuit for compensating for attenuation of different cellular communication standards. ^ 15 cl, 9 dwg |
