Abstract
An array of carbon nanotube electron sources to make an integrated array of RF (radio frequency) sources in a single vacuum envelope. The RF sources can be printed circuit traveling wave tubes.
Claims10
An RF array comprising:
- a first printed traveling wave tube array (“PTWT”) comprising:
- first slow wave circuitry printed on a first substrate;
- a first collector printed on the first substrate;
- and
- a first cold field emission cathode for emitting electrons towards the first slow wave circuitry;
- and
- an antenna array coupled to the first PTWT.
