Accurate prediction of PHEMT intermodulation distortion using the nonlinear discrete convolution model [PDF]

open access: yes, 2002
A general-purpose, technology-independent behavioral model is adopted for the intermodulation performance prediction of PHEMT devices. The model can be easily identified since its nonlinear functions are directly related to conventional DC and small ...

Temperature dependence of PHEMT noise parameters

open access: yes, 1996
To compute and optimize the temperature performance of low noise amplifiers requires not only the temperature coefficients of all the small signal equivalent circuit parameters at the operating bias, but also the temperature dependence of the noise parameters.

Thermo-mechanical analysis of GaAs devices under temperature-humidity-bias testing

open access: yes, 2015
International audienceAccelerated life tests on microelectronic devices are needed to estimate their degradation under severe environment. THB (Temperature Humidity Bias) [1] at 85°C and 85%RH (relative humidity) is commonly used for reliability studies.

Novel Approach to Design Ultra Wideband Microwave Amplifiers: Normalized Gain Function Method [PDF]

open access: yes, 2013
In this work, we propose a novel approach called as “Normalized Gain Function (NGF) method” to design low/medium power single stage ultra wide band microwave amplifiers based on linear S parameters of the active device.

Enhancing the Accuracy of Microwave Element Models by Artificial Neural Networks [PDF]

open access: yes, 2004
In the recent PSpice programs, five types of the GaAs FET model have been implemented. However, some of them are too sophisticated and therefore very difficult to measure and identify afterwards, especially the realistic model of Parker and Skellern.
