INTEGRATED POWER AMPLIFIER WITH BIAS CONTROL AND HARMONIC TERMINATION

Apparatuses and systems implementing an amplifier module are described. The amplifier module can include a substrate. A driver amplifier die, a splitter network, an output amplifier die, a bias controller, and a combiner network can be coupled to the substrate. The driver amplifier die can be configured to receive an input radio frequency (RF) signal. The splitter network can be configured to split an intermediate RF signal outputted from the driver amplifier die into first and second RF signals. The output amplifier die can be configured to receive the first and second RF signals. The bias controller can be configured to bias the driver amplifier die and the output amplifier die. The combiner network can be configured to combine first and second outputs of the output amplifier die to generate an output RF signal and terminate at least one harmonic of the output amplifier die's output impedance.
