Claim:
1. A power amplifier module comprising: a power amplifier die including a power amplifier configured to amplify a radio frequency signal, the power amplifier including a heterojunction bipolar transistor and a p-type field effect transistor, the heterojunction bipolar transistor including a collector, and the p-type field effect transistor including a semiconductor segment that includes substantially the same material as a layer of the collector of the heterojunction bipolar transistor, the semiconductor segment corresponding to a channel of the p-type field effect transistor; a load line electrically connected to an output of the power amplifier and configured to provide impedance matching at a fundamental frequency of the radio frequency signal; and a harmonic termination circuit electrically connected to the output of the power amplifier and configured to terminate at a phase corresponding to a harmonic frequency of the radio frequency signal.
