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 ONOFF isolation Device miniaturization Increased interaction efficiency Improved linearity Decreased harmonic power.
