Apparatus and methods for power amplifier output matching

An output matching circuit for a power amplifier that amplifies a radio frequency signal having a fundamental frequency, the output matching circuit comprising:

• an input configured to receive an amplified radio frequency signal from a power amplifier;
• first and second outputs;
• a first matching circuit electrically connected between the input and the first output, the first matching circuit configured to suppress harmonics of a fundamental frequency of the amplified radio frequency signal when the amplified radio frequency signal is within a first band;
• and
• a second matching circuit electrically connected between the input and the second output, the second matching circuit configured to suppress harmonics of the fundamental frequency of the amplified radio frequency signal when the amplified radio frequency signal is within a second band different from the first band.

A mobile device comprising:

• an antenna;
• a power amplifier configured to amplify a radio frequency input signal having a fundamental frequency, the power amplifier including an input configured to receive the radio frequency input signal and an output configured to generate an amplified radio frequency signal for transmission via the antenna;
• and
• an output matching circuit including an input configured to receive the amplified radio frequency signal, a first output, a second output, a first matching circuit electrically connected between the input of the output matching circuit and the first output, and a second matching circuit electrically connected between the input of the output matching circuit and the second output, the first matching circuit configured to suppress harmonics of the fundamental frequency when the radio frequency input signal is within a first band, and the second matching circuit configured to suppress harmonics of the fundamental frequency when the radio frequency input signal is within a second band different from the first band.
