CASCODE AMPLIFIER SEGMENTATION FOR ENHANCED THERMAL RUGGEDNESS

摘要

According to some implementation, a power amplifier includes a plurality of pairs of transistors, each pair of transistors including a common emitter transistor and a common base transistor arranged in a cascode configuration. The power amplifier further includes electrical connections implemented to connect the plurality of pairs in a parallel configuration between an input node and an output node. According to some implementations, the electrical connections are configured to distribute a collector current to all of the common base transistors to thereby reduce likelihood of damage to one or more common base transistors during a thermal run-away event.
