Abstract
The purpose of this work is to develop a complex for research and measurement of parameters and characteristics of radio technical facilities (RTF). The complex is designed to generate ultra-wideband signals from 2 to 298 GHz in measuring systems that require the generation of complex radio signals: antenna measurements, research of radar characteristics and electrodynamic parameters of materials. The task is achieved by the fact that the quadrature signals of the results of the summation of the useful signal with noises that interfere with reflections and interference, are formed in the complex. Coherent signals are generated in analog form over four channels, and replaceable modules of the infrared frequency carrier and antennas form signals that are radiated into space. Replaceable blocks provide cascaded sequential mixing of the main signal with the local oscillator frequency. The selection of replaceable modules with a given local oscillator frequency makes it possible to provide signal radiation in the microwave and EHF frequency ranges.
