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 <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$60-90 \text{GHz}$</tex> and a radio frequency range from <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$285-325 \text{GHz}$</tex>. 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 <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$60-90 \text{GHz}$</tex>. The frontends are produced in a 35 nm InGaAs mHEMT technology for long range THz data transmission.
