Title 125 GHz Frequency Doubler using a Waveguide Cavity Produced by Stereolithography Degree of recognition International Media type Web Country/Territory United States Date 25/01/22 Description This technical paper reports on the first Schottky diode frequency doubler with a split-block waveguide structure fabricated by a high-precision stereolithography (SLA) printing process. The printed polymer waveguide parts were plated with copper and a thin protective layer of gold. The surface roughness of the printed waveguide parts has been characterized and the critical dimensions measured, revealing good printing quality as well as a dimensional accuracy that meets the tight tolerance requirements for sub-terahertz active devices.
Read this technical paper to learn how micro-precision 3D printing was used to fabricate a 125 GHz frequency doubler using a waveguide.Producer/Author BMF Boston Micro Fabrication Persons Yi Wang
