Abstract :
We model the thermal performance of the large thermal via which under the collector-up heterojunction bipolar transistor (HBT) by using a finite element method. A compact thermal-via packaging of GaInP/GaAs collector-up HBTs has been designed and calculated. The results indicate that the configuration can be further reduced by 29% to meet the requirement of small high-power amplifiers for cellular-phone communication systems.
