NettetAbstract:In the course of the DARPA HiFIVE (High Frequency Integrated Vacuum Electronics) program, we have investigated various MEMS techniques for micro-fabrication of electronic circuits built in a 0.22 THz traveling wave tube (TWT) amplifier. NettetBefore that, all electronic equipment used vacuum tubes, because vacuum tubes were the only electronic components that could amplify—an essential capability in all electronics. The transistor, which was invented by John Bardeen and Walter Houser Brattain while working under William Shockley at Bell Laboratories in 1947, [8] could …
