Field-Emitter Arrays for RF Vacuum Microelectronics

Abstract

This report covers a research and development program on the Spindt- type field-emitter-array cathode with a view toward eventual applications in microwave amplifiers. The goals of this first phase have been set at 5 mA total emission with a current density of 5 A/sq.cm for at least 1 hr, and demonstrated modulation of the emission current at a frequency of 1 GHz. Our approach has been to identify methods of adapting and modifying the basic cathode structure for microwave operation and to experimentally investigate means of implementing those methods.
