A commercial pulsed-IV system is used to test a GaN HEMT with the purpose of extracting exponential time constants used for dynamic electro-thermal and charge-carrier trapping models. The time constants of these different physical phenomena can not o

This paper presents an analysis on the dependence of the pulsed I-V characteristics of GaN HEMTs under varying quiescent drain voltage (V dsq ) conditions, and a new model is developed for this behavior. It is found that three device parameters chang

S-parameter data files remain the most commonly available “model” for representing passive devices in the microwave industry. As exemplified herein, physically-motivated equivalent circuit models can be setup to scale accurately with part-value,

Clarifications are made related to the use of passive devices for noise parameter test system validation. It is pointed out that in the case of the use of a passive device, such as a mismatched attenuator, the minimum noise figure and optimal noise r
