Enhanced power amplifier efficiency through elimination of matching network

A wireless device comprising:

• a transceiver configured to generate a radio-frequency (RF) signal;
• a front-end module (FEM) in communication with the transceiver, the FEM including a packaging substrate configured to receive a plurality of components, the FEM further including a power amplification system implemented on the packaging substrate, the power amplification system including a plurality of power amplifiers (PAs), each PA configured to receive and amplify a radio-frequency (RF) signal, the power amplification system further including an output filter coupled to each of the PAs by an output path that is substantially free of an impedance transformation circuit;
• and
• an antenna in communication with the FEM, the antenna configured to transmit the amplified RF signal.

A method for processing a radio-frequency (RF) signal, the method comprising:

• amplifying the RF signal with a power amplifier (PA);
• routing the amplified RF signal to an output filter substantially without impedance transformation;
• and
• filtering the amplified RF signal with the output filter.
