Abstract :
The first completely physical coupled electro-thermal model, suitable for large signal simulation of MESFET and HEMT based MMICs and MMIC arrays, on a timescale suitable for CAD, is presented. The model is validated experimentally by high resolution thermal imaging of a MMIC 38 GHz 3-stage balanced amplifier, mounted on a Cu/FR-4 substrate and cooled entirely by natural convection and radiation into free space.
