A Superheterodyne 300 GHz InGaAs Receiver and Transmitter Chipset for 6G and Beyond Applications

This paper presents a superheterodyne receiver and transmitter chipset operating at an intermediate frequency from 60-90 GHz and a radio frequency range from 285-325 GHz. In this paper the continuous wave on-wafer measurements are presented. For the transmitter an output referred 1 dB compression point of 0 dBm is achieved over the entire intermediate frequency range. The conversion gain of the receiver was measured to be over 12 dB from 60-90 GHz. The frontends are produced in a 35nm InGaAs mHEMT technology for long range THz data transmission.
