Electroplated Helical Slow-Wave Structures For High Frequency Signals
Inventors: Max Lagally, Matthew Dwyer, Daniel van der Weide, Abhishek Bhat, Francesca Cavallo, Divya Prakash
Traveling-wave tube amplifiers and methods for making slow-wave structures for the amplifiers are provided. The SWSs include helical conductors that are self-assembled via the release of stressed electrically conductive strips from a sacrificial material. The helical conductors can be electroplated post-self-assembly to fortify the helix, reduce losses, and tailor the dimensions and operating parameters of the helix.
