POWER AMPLIFICATION SYSTEM WITH SHARED COMMON BASE BIASING

摘要

Power amplification system with shared common base biasing. A power amplification system can include a plurality of cascode amplifier sections. Each one of the plurality of cascode amplifier sections can include including a first transistor and a second transistor. The power amplification system can include a plurality of common emitter biasing components. Each one of the plurality of common emitter biasing components can be coupled to a base of the first transistor of a respective one of the plurality of cascode amplifier sections and can be controllable to bias the first transistor of the respective one of the plurality of cascode amplifier sections. The power amplification system can include a common base biasing component coupled to a base of the second transistor of each of the plurality of cascode amplifier sections and controllable to bias the second transistor of each of the plurality of cascode amplifier sections.
