Abstract: Provided herein are apparatus and methods for power enhancement of self-biased distributed amplifiers with gate bias networks. By sampling output power a gate bias network with a filter network can adjust gate bias so as to improve the P1 dB compression point and the Psat saturation power level of a self-biased distributed amplifier. Advantageously the filter network can be derived using passive components thereby making it an easy to implement and cost effective approach to improve linearity and output power.
