Abstract

A sequenced transmit muting wideband power amplifier is provided that includes at least one pre-driver stage having at least a first pre-driver and a second pre-driver. A mute switch selectively establishes a communication path between the first and second pre-drivers or couples the second pre-driver to a termination resistor. A pre-driver switch selectively activates/deactivates the first and second pre-drivers. A driver stage is in communication with the pre-driver stage and includes a first driver. A final amplifier stage is in communication with the driver stage and includes at least one second driver. At least one S-NBS switch is configured to selectively activate/deactivate the first driver and second driver. A controller is configured to activate the at least one pre-driver switch, the mute switch, the at least one S-NBS switch to selectively place the amplifier in one of a transmit mode and a mute mode.
