MICROWAVE RECEIVING DEVICE Russian patent published in 2019 - IPC H04B1/26 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to radio engineering and can be used in broadband UHF radio receiving devices. UHF radio receiving device comprises first, second, third, fourth, fifth, sixth and seventh power dividers per two channels; first, second, third, fourth, fifth, sixth and seventh filters of intermediate frequency; first, second, third and fourth heterodynes; as well as first and second frequency identification units, control unit and switch. In the microwave radio receiving device, signs of useful signals are used, which are formed in a two-channel system with different tuning of heterodynes in channels and with identical ranges of intermediate frequencies.

EFFECT: design of a device which increases resolution of signals with close values of carrier frequencies falling in the same instantaneous frequency sub-range, with a wide range of intermediate frequencies and a wide dynamic range of power of input signals; wherein wide frequency band of input signals and wide band of intermediate frequencies up to one octave maintains a wide dynamic range of power of input signals greater than 80 dB.
