Abstract
A power amplifier includes a bipolar transistor and a self-adaptive bias network situated between an RF input and the base of the bipolar transistor. The self-adaptive bias network suppresses the low frequency even-order intermodulation components. The self-adaptive bias network stabilizes a DC bias voltage to provide a substantially constant base-emitter voltage and provides an increased DC base current with increased input power when the power amplifier is operating within the nonlinear region.
