V-band Microwave Power Module Based on an Overmoded TWT

ABSTRACT: We propose to design fabricate and test a novel overmoded V-Band (71-76 GHz) Traveling Wave Tube (TWT) for eventual use in a Microwave Power Module (MPM). The TWT and the solid-state driver system will be designed for future integration in a compact MPM. The TWT will be designed to generate>50 W of output power with>30 dB linear gain and power added efficiency>30%. The overmoded circuit coupled with multiple electron beams will enable scaling this technology to W-band and terahertz (THz) frequencies for a range of military and commercial applications in the areas of radar, satellite and high speed point to point communication and advanced scientific research in the areas of imaging and spectroscopy. BENEFIT: The proposed TWT amplifier or the MPM can be employed for commercial satellite communications and high bandwidth point to point digital radio links. A W-band or THz frequency device can be used for other commercial applications such as long stand-off range security imaging and advanced scientific research in the areas of sensitivity enhanced Nuclear Magnetic Resonance (NMR) by Dynamic Nuclear Polarization (DNP) and Electron Paramagnetic Resonance (EPR) spectroscopy.
