Deflection microwave amplifier with field emission arrays
We analyze a new class of microwave and millimeter-wave amplifiers, based on the deflection of collimated microscopic electron beams with high-current density and low-voltage from field-emission arrays. The deflection concept may be applied in two ways: as microelectronic amplifiers or as bunched beam cathodes to power conventional amplifier configurations such as Klystrodes and traveling wave tubes. We found that the gain-bandwidth product, f/sub T/, depends only on the electron beam energy, current density and emittance, and is independent of beam width and total current. For line current of 20 /spl mu/Aspl mu/m, emittance /spl epsivsub nspl les/1.4/spl times/10/sup -6/ mm, we find that f/sub T/>200 GHz.<>
