It is well known that, in the millimeter (mm-wave) and sub-mm-wave range, on-wafer S-parameter measurements are often inaccurate and suffer from serious systematic artifacts. In this paper, we confirm that these artifacts are related to spurious wave

2016 IEEE MTT-S International Microwave Symposium (IMS).
In this paper we present a new small signal multiport modelling approach for III–V High Electron Mobility Transistors (HEMT) that is capable for internal transistor analysation and optimization as well as scaleable in gate width and finger-number.
