    摘要: A bi-directional amplifier (10) for a transceiver module for amplifying both transmit signals and receive signals propagating in opposite directions. The amplifier (10) includes first and second common gate FETs (22, 24) electrically coupled along a common transmission line (20). A first variable matching network (28) is electrically coupled to the transmission line (20) between a transmit signal input port (12) and the first FET (22), and a second variable matching network (30) is electrically coupled to the transmission line (20) between a receive signal input port (14) and the second FET (24). An interstage variable matching network (32) is electrically coupled to the transmission line (20) between the first and second FETs (22, 24). A DC voltage regulator (34) provides a DC bias signal to the matching networks (28, 30, 32) and the FETs (22, 24) so that different signal amplifications and different impedance matching characteristics can be provided for the transmit signal and the receive signal.
