ABSTRACT:
A transceiver module includes a bi-directional amplifier having a pair of symmetric signal paths for amplification of both transmit and receive signals is described. The amplifier is a bi-directional amplifier and includes a pair of symmetric signal paths. The amplifier is disposed between a pair of r.f. switches to provide a pair of signal paths between two terminals of the module. A phase shifter is coupled between one of the terminals of the module and one of the r.f. switches, wherein the second terminal of the module is coupled directly to the other one of the pair of switches.
