Abstract
Embodiments provide a radio frequency (RF) switching apparatus including an RF switching device configured to receive an RF input signal and to pass an RF output signal if the RF switching device is activated. The RF switching apparatus may include a control terminal to receive a control signal to activate the RF switching device. A gate resistor may be coupled between the control terminal and a gate terminal of the RF switching device. A helper circuit may be coupled in parallel with the gate resistor. The helper circuit may be configured to provide a temporary conductive path between the control terminal and the gate terminal in response to a state transition of the control signal. The helper circuit may provide an open circuit between the control terminal and the gate terminal during a steady state of the control signal between state transitions.
