Development of Electron Tube for Switching Radio Frequency Power

Abstract

A new type of gas triode has been developed to switch power from a single 1000-megacycle oscillator between two loads in less than a microsecond. The volume of the grid-anode region inside the tube is kept small so that r-f power up to about 8 kilowatts will not initiate a gas discharge in the tube. When a negative voltage of more than about 15 volts is applied to the cathode, the breakdown of the gas reduces the grid-anode impedance to a very low value. Since the recovery time is about 8 microseconds, two tubes, each in a tuned circuit, are used in the switching arrangement.
