Abstract:
Apparatus and methods for power amplifier biasing are disclosed herein. In certain implementations, a power amplifier system includes a power amplifier bias circuit and a power amplifier. The power amplifier bias circuit includes a reference current source that generates a reference current, a bipolar reference transistor, and a transimpedance amplifier that amplifies a difference between a collector current of the bipolar reference transistor and the reference current, and that provides a base bias voltage to a base of the bipolar reference transistor. The power amplifier generates a radio frequency output signal at an output based on amplifying a radio frequency input signal received at an input. The power amplifier includes a bipolar power amplifier transistor including a base biased by the base bias voltage such that the power amplifier has a substantially flat gain response versus time.

Claim (Index 11):
The packaged module of  claim 10  wherein the semiconductor die further includes an amplifier including an input electrically connected to the collector of the reference bipolar transistor and an output configured to control a base voltage of the reference bipolar transistor.
