Abstract :
We are developing a wideband 95-GHz, 200-W TWT powered by a 20-kV, 122-mA electron beam. The serpentine waveguide circuit is fabricated by UV-LIGA using an embedded monofilament, which produces an all-copper structure with beam tunnel. Simulations predict 37 dB small-signal gain and 245 W maximum output power.
