FIELD: radio engineering, communication.
SUBSTANCE: invention consists in receiving and transmitting signals simultaneously through the same antenna; the output of the antenna is connected to the input of the forward arm of an additional directional coupler; the input of the amplifier is connected to the output of the tapping arm of the directional coupler, and the output of the amplifier is connected to the output of the forward arm of the directional coupler, wherein the amplifier gain should not exceed the decoupling between the forward and tapping arms of the directional coupler.
EFFECT: invention enables to exclude one antenna from the composition of the transceiver, thereby improving its weight and size characteristics.
