摘要

We present an overview of additive fabrication methods for upper-millimeter-wave traveling-wave tube (TWT) amplifier slow-wave circuits, including ultraviolet lithography and Cu electroforming (UV-LIGA); 3D-printed mold electroforming (3D-PriME); and direct 3D printing in photopolymer with Cu plating. We describe example fabrication processes for traveling-wave circuits spanning the frequency range 94 GHz to 1 THz and present test data.
