CONVERTING TRANSMIT-RECEIVE MODULE OF A DIGITAL ANTENNA ARRAY WITH A TWO-LEVEL CONTROL (VARIANTS) Russian patent published in 2019 - IPC H01Q3/00 H01Q21/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to radio engineering, in particular to converting transmit-receive modules (CTRM), and can be used in radar and communication systems for operation in digital antenna arrays (DAA) using digital diagram formation techniques for transmission and reception, and digital signal processing methods. Converting transmit-receive module of a digital antenna array with two-level control contains bidirectional (reversible) frequency converter 1, first ferrite transmit-receive switch 2 on ferrite circulator, power amplifier 3, second ferrite transmit-receive switch 4, low-noise amplifier 5. Between an output/input of bidirectional (reversible) frequency converter 1 and the first arm of first transmit-receive switch 2, bidirectional (reversible) controlled phase shifter 6 is additionally introduced. Module can be multichannel.

EFFECT: obtaining an additional (second) channel for controlling CTRM, providing temperature stability and reliability, reducing the number of connections in distribution systems, simplifying the control system and the entire DAA.
