Abstract

Northrop Grumman Electronic Systems is developing compact, efficient amplifiers above 100 GHz as part of the DARPA High Frequency Integrated Vacuum Electronics (HiFIVE) program. Sub-components are being demonstrated for a compact 100 W amplifier operating at 220 GHz including a low attenuation folded waveguide (FWG) circuit and a high aspect ratio electron beam propagating through a FWG circuit at 95% transmission efficiency. The HiFIVE program relies upon a robust FWG circuit where a TE₁₀ mode propagates through a serpentine, rectangular waveguide as the electron beam travels through a beam hole along the axis of the circuit. The FWG slows the RF phase velocity relative to the electron beam, enabling synchronous interaction and net gain.
