A 60 GHz single-chip CMOS transceiver for high-definition video transmission system application

A 60 GHz simple and small size sub-harmonic transceiver which incorporates with 45 degree phase shifter to implement higher order shift keying modulation ability is realized. The single chip transceiver can be transmitting mode or receiving mode by switching the single pole double throw (SPDT) easily. This transceiver is fabricated in a 90 nm CMOS process and occupied 2.8 mm2 areas. The measured 3 dB bandwidth of up-conversion gain and down-conversion gain is 6 GHz and 5 GHz individually.
