Invention concerning to antenna technique and may be used for full testing of transmit-receive modules, which include in active phase array antenna AAPA of radiotechnical systems of different functions. Goal of invention — increasing of testing level of AAPA transmit-receive module. Device determines attenuation discrete and intervals inserted by controlled attenuators of each transmit — receive element of module, discrete and intervals of phase shifts inserted by the same phase -shifters, dispersions of complex transmitter element characteristics in signal receive and transmit modes, and polarization characteristics of waves radiated by module elements.

A designing of radio-measurement circuits, which are the parts of the antenna complex near-field automatic measurement systems of short millimeter waveband, are discussed. In the offered circuits the quadrature processing of a useful signal is used with account of an analysis of centimeter waveband similar radio-measurement circuits.
