Abstract
A bidirectional time-division duplexing transceiver circuit includes a first and a second bidirectional phase-shift circuit, and a bidirectional amplifier circuit including a first amplifier circuit and a second amplifier circuit. The first amplifier circuit and the second amplifier circuit are coupled via double-pole-double-throw (DPDT) switches to radio-frequency (RF) antennas and the first and the second bidirectional phase-shift circuits. The (DPDT) switches enable the first amplifier circuit and the second amplifier circuit to be operable simultaneously as transmit (TX) path amplifiers in a first time slot and as a receive (RX) path amplifiers in a second time slot.
