Abstract
The output impedance matching network of a power amplifier module is improved by the addition of an intermediate set of bonding pads in close proximity to a power transistor in the power amplifier module. A tunable set of bond wires extend from the intermediate bonding pads to a transmission line that is coupled to the output of the power amplifier module. The tunable bond wires allow the inductance of the impedance matching network to be tuned and optimized.
