Abstract
An amplifier system for radio frequency hot switching of a power amplifier can include a field-effect transistor, a forward biasing network, and a reverse biasing network. The forward biasing network is configured to provide a positive bias voltage to a gate terminal of the field-effect transistor, and the reverse biasing network is configured to provide a negative bias voltage to the gate terminal, with resistance of both biasing networks selected to independently control an on and off-switching time of the field-effect transistor. The independent on and off-switching time can allow for rapid 'hot switching' in a connected power amplifier while the power amplifier is energized, while reducing spurious emissions of radio frequency signals by the power amplifier.
