Abstract
A multi-band power amplifier module includes a first power amplifier that amplifies a first input radio frequency signal in a first frequency band in response to a first bias control signal. A second power amplifier amplifies a second input radio frequency signal in a second frequency band in response to a second bias control signal. A first bias control circuit produces the first bias control signal and a second bias control circuit produces the second bias control signal in response to step gain signals received at a step gain terminal.
