Microfabricated mm-wave TWT platform for wireless backhaul

Teraphysics Corporation is developing a suite of miniature mm-wave TWTs for application to wireless backhaul. These devices are based on the 94 GHz TWT that was presented at IVEC 2014. This TWT, which weighs only .5 kg and has the footprint of a credit card, will serve as a platform for the miniature devices needed to fit into the limited space available on typical backhaul sites, such as telephone poles or street lights. The first application will be in E-Band. However, the sweet spot for the Teraphysics miniature helical amplifiers will be in the atmospheric windows centered at 140 and 240 GHz.
