Methods and apparatus for reducing switching time of rf fet switching devices

A FET switch stack comprising:

• a stacked arrangement of FET switches proceeding from a bottom FET switch to a top FET switch, wherein a position of a FET switch inside the stacked arrangement defines a corresponding height in the stacked arrangement, said height going from a minimum height corresponding to the bottom FET switch to a maximum height corresponding to the top FET switch, the stacked arrangement connected at one end to an RF terminal configured to be coupled to an RF signal, the stacked arrangement configured to have an ON steady state where the FET switches are ON, an OFF steady state where the FET switches are OFF, and transition states where the FET switches are transitioning from ON to OFF and vice versa;
• and
• a plurality of gate feed arrangements, each gate feed arrangement being coupled to the stacked arrangement at a different height of the stacked arrangement and comprising one or more bypass switches connected across one or more common gate resistors, said each gate feed arrangement configured to feed a control signal to gates of the FET switches to control the ON steady state, the OFF steady state and the transition states of the stacked arrangement.
