GaAs Resistor Model Predicting Harmonic, Transient and Breakdown

From Skyworks Solutions, Inc.

A comprehensive nonlinear model of GaAs resistor is
developed based on DC, pulse and power measurements. The
model accounts for electrical and thermal feathers such as
velocity saturation, self-heating and breakdown effects. The
resistor nonlinearity is mainly due to the velocity saturation, and
enhanced by self-heating effect. The model provides accurate
performances in DC, transient and harmonic balance
simulations, and is a useful tool for monolithic microwave
integrated circuits (MMICs) development.

RF Upconverters and RF Downconverters
RF upconverters and RF downconverters are integrated assemblies that convert microwave signals to another frequency range for further processing. Generally, they are designed to produce an output signal frequency for a particular frequency band.
RF Frequency Converters
RF frequency converters are integrated component assemblies required for converting microwave signals to lower (or intermediate) or higher frequency range for further processing.  
RF Filters and Microwave Filters
RF filters and microwave filters are devices that pass or reject signals by frequency. Basic types include bandpass filters, band reject filters, low pass filters, and high pass filters.
RF Band Pass Filters
RF band pass filters are active or passive circuits that pass signals from a specific frequency band and reject signals from out-of-band frequencies. Surface acoustic wave (SAW) filters, crystal filters, and cavity filters are types of band pass filters.
