DEVICE FOR STORING FREQUENCIES OF MICROWAVE SIGNALS Russian patent published in 2014 - IPC G11C7/16 H04B1/26 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to radio engineering and can be used in receivers which are part of radio monitoring and radio countermeasure equipment. The device for storing frequencies of microwave signals consists of first and second frequency conversion stages. The first frequency conversion stage includes: eight mixers, four power dividers, two adders having three inputs each, four switches, four heterodynes and six electrical filters. The second frequency conversion stage includes: an input power divider, an output adder, two π/2 phase sections, two input mixers and two output mixers, a heterodyne and two digital memory devices.

EFFECT: controlling the operating frequency range and dynamic range by suppressing combination frequencies, arising in the second stage, in the first frequency conversion stage.
