Summary: 
We developed a 300-GHz high gain amplifier MMIC in 75-nm InP high electron mobility transistor technology. We approached the issues with accurate characterization of devices to design the amplifier. The on-wafer through-reflect-line calibration technique was used to obtain accurate transistor characteristics. To increase measurement accuracy, a highly isolated structure was used for on-wafer calibration standards. The common source amplifier topology was used for achieving high gain amplification. The implemented amplifier MMIC exhibited a gain of over 25 dB in the 280-310-GHz frequency band.
