HBT power devices and circuits
Abstract
The status of the power HBT technology is reviewed. The advances made in the electrical and thermal design of unit-cells are examined to identify the present and near future applications in microwave power amplifications. The current status of the technology is such that AlGaAs/GaAs HBTs have become suitable for most microwave and especially for commercial L/S-band frequency applications. The performance is not yet adequate for mm-wave applications, which may require alternative material technologies.
