This paper describes Monolithic microwave integrated circuits (MMICs) and MMIC modules for 120 GHz 10-Gbps or more wireless data communications using ASK and QPSK modulation schemes. Record transmission distance of 5.8 km was established using ASK architecture MMICs at a data rate of 10-Gbps and a carrier frequency of 125 GHz. QPSK modulator and demodulator show that they performs full function in back-to-back test at a carrier frequency of 128 GHz at 10-Gbps. Furthermore, the QPSK chips was improved and integrated with low noise amplifier or power amplifier. In result, this QPSK transceiver chipset showed 22.2-Gbps error-free transmission at an output power of 7 dBm and received power -35 dBm in back-to-back measurement.
