Abstract
According to at least one aspect of the disclosure, a front-end module is provided comprising an input configured to receive a radio-frequency signal, an output configured to be coupled to an antenna, a balun coupled to the output, one or more power amplifiers coupled to the input, and an inverter coupled between the one or more power amplifiers and the balun, the inverter being configured to provide output impedance matching to the one or more power amplifiers.
Claims20
A front-end module comprising:
- an input configured to receive a radio-frequency signal;
- an output configured to be coupled to an antenna;
- a balun coupled to the output;
- one or more power amplifiers coupled to the input;
- and
- an inverter coupled between the one or more power amplifiers and the balun, the inverter being configured to provide output impedance matching to the one or more power amplifiers.
A method of processing a radio-frequency signal comprising:
- providing a front-end module having
- an input configured to receive a radio-frequency signal,
- an output configured to be coupled to an antenna,
- a balun coupled to the output,
- one or more power amplifiers coupled to the input, and
- an inverter coupled between the one or more power amplifiers and the balun,
- receiving, by the one or more power amplifiers from the input, the radio-frequency signal;
- providing, by the one or more power amplifiers, an amplified signal to the inverter;
- and
- providing, by the inverter, output impedance matching to the one or more power amplifiers responsive to receiving the amplified signal.
