POWER AMPLIFIER HAVING STAGGERED CASCODE LAYOUT FOR ENHANCED THERMAL RUGGEDNESS

摘要

Power amplifier having staggered cascode layout for enhanced thermal ruggedness. In some embodiments, a radio-frequency (RF) amplifier such as a power amplifier (PA) can be configured to receive and amplify an RF signal. The PA can include an array of cascoded devices connected electrically parallel between an input node and an output node. Each cascoded device can include a common emitter transistor and a common base transistor arranged in a cascode configuration. The array can be configured such that the common base transistors are positioned in a staggered orientation relative to each other.
