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. The module has first and second rows of pins oppositely positioned on the module and coupled to the first and second power amplifiers and first and second bias circuits.
