    For radiometric application in the frequency range around 325 GHz, two low noise amplifier millimeter-wave monolithic integrated circuits have been developed. They use metamorphic high electron mobility transistors with a gate-length of 35 nm. The first amplifier only uses transistors in common-source configuration, whereas the second only employs transistors in cascode configuration. Their simulated and measured performance is compared to find which configuration is advantageous for the design of low noise amplifiers in this frequency range.
