Abstract
A power amplification system with shared common base biasing is disclosed. A method for power amplification at a controller of a power amplification system comprising a plurality of cascode amplifier sections can include receiving a band select signal indicative of one or more frequency bands of a radio-frequency input signal to be amplified and transmitted. The method may further include biasing a common base stage of each of the plurality of cascode amplifier sections, and biasing a common emitter stage of a subset of the plurality of cascode amplifier sections.
