ABSTRACT:
An amplification circuit and scaling method are configured to apply optimum biasing characteristics such that a multistage power amplifier operates according to defined performance characteristics. The operating conditions of the multistage amplifier are optimized by applying independent bias voltages to each stage within the multistage amplifier while operating in a maximum power output range. To achieve optimum or near-optimum operating conditions, each bias voltage is independently scaled according to a specific power output level.
