Document Type and Number:
WIPO Patent Application WO/2020/166196
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a bidirectional amplifier that can be reduced in size, even when a plurality of amplifying units have respectively different performances. This bidirectional amplifier (11) has: a first amplifying unit (111) for amplifying a first signal inputted from a first terminal (p1) and outputting the amplified signal from a second terminal (p2); a second amplifying unit (112) for amplifying a second signal inputted from the second terminal (p2) and outputting the amplified signal from the first terminal (p1), the second amplifying unit (112) having a compensation element (C111) and a compensation element (C112) for compensating the degradation of the performance of the first amplifying unit (111); and a control unit (113) for controlling the operation of the first amplifying unit (111) and the operation of the second amplifying unit (112).
