Time Division Duplex Beam Switching System Using a Common Multi-Port Junction Transceiver

The paper proposes a compact multi-port transceiver for time division duplex systems. Both uplink and downlink transmissions of the transceiver are combined in one six-port junction. To validate the performance of the modulator and demodulator, prototype circuits are simulated with different PSK/QAM signals at the carrier frequency of 61 GHz. The obtained results indicate an excellent performance of the system, as well as implemented TDD beam switching antenna networks.
