Abstract
Radio frequency (RF) switch circuitry is disclosed having a field-effect transistor with a drain, a source, and a gate, wherein the gate is driven by switch driver circuitry having a control terminal for receiving switch-on and switch-off signals and a driver terminal for outputting on-state and off-state voltages. The switch driver circuitry is configured to respond to the switch-on signal by generating the on-state voltage that when applied to the gate allows an RF signal to pass between the drain and the source and respond to the switch-off signal by generating the off-state voltage that when applied to the gate blocks the RF signal from passing between the drain and the source. A low-pass filter has an inductor coupled between the gate and the driver terminal, wherein a direct current (DC) path between the gate and the driver terminal has a total DC resistance of no more than 100 Ω.
