Abstract
Modelling of thermal effects of GaAlAs/GaAs HBTs d.c. and r.f. charact eristics is presented. The thermal resistance value is determined expe rimentally and introduced in a model. Good agreement between measured results and those from modelling is demonstrated. The r.f. performance shows a good stability at high temperature (f(max) is reduced by abou t 12% due to temperature rise). For the high signal mode, the simulati on of a power amplifier at 3 GHz is also carried out with and without temperature effects.
