Operation of a Low-Voltage High-Transconductance Field Emitter Array TWT; Briefing charts

摘要

Implementation of 'cold cathodes' as an electron source for RF vacuum devices can have a significant impact on many aspects of device operation. Cold Cathode Impact on RF Device Operation: No cathode wearout mechanism * Room temperature operation * Eliminate heater power * High current density operation * Instant turn-on * Eliminate HV modulator * Multi-mode operation * Infinite ON/OFF isolation * Device miniaturization * Increased interaction efficiency * Improved linearity * Decreased harmonic power.
