Annotation: The article presents a circuit of an ultra-wideband pin-diode switch for two channels with different operating frequency ranges: DC-18 GHz and 18–26.5 GHz. A topology model of a microwave monolithic integrated circuit (MMIC) based on quasi-vertical GaAs pin diode technology of Miсran JSC is described. Comparison of simulation results and experimental measurement data of manufactured MMICs is performed. The use of the integrated circuit of the switch is possible as a part of the switching nodes of the measuring microwave equipment.
