TRANSCEIVER MODULE Russian patent published in 2003 - IPC

FIELD: antennas. SUBSTANCE: first radiator of transceiver module is connected to first side of first Y-junction circulator whose second side is connected to input of transmitting channel incorporating series-connected first controllable phase shifter, controllable attenuator, first gate, and power amplifier whose second input is connected to controllable pulse modulator. Connected to power amplifier output is first side of second Y-junction circulator whose second side is coupled with second radiator and third one, with first side of third Y-junction circulator; connected to third side of the latter is matched load and to second one, receiving channel input. It has series- connected protective gear, low-noise amplifier, second gate, and second controllable phase shifter whose output is connected to third side of first Y-junction circulator. Control inputs of first and second controllable phase shifters, attenuator, and controllable pulse modulator are coupled with respective outputs of control microprocessor unit. EFFECT: simplified design and enhanced reliability of transceiver module. 1 cl, 1 dwg
