Abstract
A system and method are provided for maintaining a consistent operating condition of a power amplifier power amplifier across a range of operating temperatures. The power amplifier is provided with an input bias voltage (Vbias) that adjusts with temperature to compensate for the temperature dependent change of the power amplifier's base-emitter voltage drop Vbe. This maintains a consistent operating condition in the power amplifier, which reduces temperature-dependent changes in the amplifier's gain.
