  • CIRCUITS AND METHODS FOR BIASING POWER AMPLIFIERS
    Publication number: 20180175814
    Abstract: Circuits and methods for biasing power amplifiers. In some embodiments, a power amplifier circuit can include a transistor having and input and an output, and configured to amplify a signal. The power amplifier circuit can further include a bias circuit configured to provide a bias signal to the input of the transistor. The power amplifier circuit can further include a switchable feed circuit implemented between the bias circuit and the input of the transistor, and configured to provide a plurality of different resistance values for the bias signal between the bias circuit and the input of the transistor.
    Type: Application

  • Switchable base feed circuit for radio-frequency power amplifiers
    Patent number: 9831841
    Abstract: Switchable base feed circuit for radio-frequency (RF) power amplifiers. In some embodiments, an RF power amplifier (PA) circuit can include a transistor having a base, a collector, and an emitter, with the transistor being configured to amplify an RF signal. The PA circuit can further include a bias circuit configured to provide a base bias signal to the base of the transistor. The PA circuit can further include a switchable base feed circuit implemented between the bias circuit and the base of the transistor. The switchable base feed circuit can be configured to provide a plurality of different resistance values for the base bias signal between the bias circuit and the base of the transistor. Such a PA circuit can be implemented in products such as a die, a module, and a wireless device.
