Wideband 307 GHz transceiver system for high speed digital wireless at 12.5 Gbps

摘要

We have developed a wideband submillimeterwave communications transceiver system, which is operating at a carrier of 307.2 GHz with bandwidth of 30 GHz. This is able to transmit and receive high speed wireless signals at 12.5 Gigabits per second (Gbps) using coherent binary phase shift keying (BPSK) modulation to about 2 meters. Measured results are reported for Bit Error Rates (BER) and constellation plot. Design considerations for this direct conversion transceiver architecture using subharmonic mixers at submillimeterwave and 76.8 GHz synthesizer will be discussed.
