Millimeter wave band TWTA compatible with nano-CNC fabrication

摘要

Airborne advanced communication systems seek high power amplifiers (∼ 50 W) in the atmospheric window around ∼ 233 GHz with a reasonably wide bandwidth (∼ 10 GHz) in a compact, light weight package. Millimeter wave — THz Traveling Wave Tube Amplifier Technology [1] is an appropriate choice for their inherent low dispersion characteristics (for wide bandwidth), high RF power handling capability, and thermal management in a reasonably compact package.
