Abstract:We present the microfabrication and cold test measurement results of serpentine waveguide amplifier circuits at 220 GHz. The circuits were fabricated using a novel embedded polymer monofilament technique combined with Ultraviolet-LIGA to simultaneously create both the beam tunnel and interaction circuits. We find remarkable characteristic matches between the measurements of the best circuits, illustrating that the process developed is able to create repeatable, highly precise circuits with high yield. It was f… Show more
