A switching system for controlling rf energy through an rf transmission medium, comprising:
- a plurality of semiconductor switching devices connected in a series configuration with the primary electrodes connected in series;
- means for providing a graduated bias on the control electrodes of said devices to establish an equal control voltage on each device between its control electrode and one of its primary electrodes for increasing the voltage capacity of said switching system and the power capacity of said rf transmission medium;
- said means for providing a graduated bias including a voltage divider network connected across the control electrodes of said semiconductor devices;
- and
- said voltage divider network including a plurality of series-connected inductors.
A switching system for controlling rf energy through an rf transmission medium and increasing the allowable voltage in said medium comprising:
- a plurality of identical field effect transistors connected in a series configuration with the drains and sources connected in series to form a conductive path between the transmission medium and ground;
- and
- a bias network connected between a bias source and the gates of said transistors for biasing the gates to provide synchronous switching of said transistors to increase the voltage capacity of said switching system and the power-capacity of said transmission medium said bias network including a plurality of series-connected inductors.
