  • Low leakage protection circuit for RF power amplifier
    Patent number: 10291191
    Abstract: The present disclosure relates to a radio frequency (RF) communications system including an RF power amplifier (PA), a bias circuit, and a protection circuit. The RF PA has an amplifier control terminal and a power supply terminal, the bias circuit is coupled to the amplifier control terminal, and the protection circuit is coupled between the bias circuit and the power supply terminal. Herein, the protection circuit is configured to reduce a current through the power supply terminal using the bias circuit via the amplifier control terminal when the RF PA is in an operation mode and a magnitude of a voltage at the power supply terminal exceeds a protection threshold. Further, the protection circuit is configured to be open and does not allow a current to pass through when the RF PA is in a standby mode.
