64QAM wireless link with 300 GHz InP-CMOS hybrid transceiver

Abstract

This letter presents a 300 GHz hybrid transceiver using CMOS and InP-HEMT, which achieves a maximum data rate of 56 Gb/s. A 300 GHz CMOS transceiver with a mixer-last transmitter mixer-first receiver is utilized to up- and down-convert the V-band IF signal to the 300 GHz-band, while InP-HEMT is used for PA and LNA design. The transceiver also achieves wireless communication in ch.13-24 (1.76 Gbaud), ch.39-44 (3.52 Gbaud), ch.52-54 (7.04 Gbaud) and ch.59 (10.56 Gbaud) with lower than −16.7 dB EVM. 64QAM modulation is also achieved for a 5 Gbaud symbol rate. The CMOS transmitter and receiver consume 0.29 W and 0.17 W from a 1 V supply, respectively, and the InP-HEMT PA and LNA consume 1.44 W from a 1.2 V supply.
