Applications Guide to 3D Printed Low-Loss Dielectric Structures Addressing Microwave/mmWave Challenges

Traditional fabrication approaches of Microwave/mmWave devices have material, geometry, tolerance, and/or repeatability challenges. New 3D printable resins with desirable Microwave/mmWave characteristics are enabling 3D DLP manufacturing of low-loss and low-dielectric constant material for prototyping and production. This whitepaper discusses applications of this 3D dielectric structure fabrication process.

Wideband RF Launches:  Much more than Footprints on PCBs

As the demand for higher frequencies and wider bandwidths continue their relentless march upward, RF connectors need to keep up with, or even exceed, demands. Mating the RF connector to a PCB or substrate requires careful consideration of several factors to get the full performance out of the connector. This white paper will provide an understanding of what makes successful launches work, what knobs to turn, and design guidelines to make connector launches perform well as the industry moves toward 100 GHz bandwidths.
