Abstract :
A physically based, large-signal HBT model is presented accounting for self-heating effects by way of a thermal circuit representing the thermal resistance of the power device. The model is validated by comparison with the experimental DC characteristics, S-parameter measurements under small-signal operation and output power measurements at 2 GHz under large-signal operation. The authors focus on the HBT frequency performance being measured using both probes and bond pads
