Rogers’ RadixTM 3D printed low-loss material has a number of applications, including RF and Microwave devices. Additionally, this game-changing RF material has both metalized and non-metalized applications. This application note will discuss the advantages of 3D printing RF components for these applications compared to traditional manufacturing methods.
Df is important for prediction of insertion loss in passive devices. If insertion loss is higher than predicted, then power transfer through a device may be too low and a higher power transmitter or more elements would be necessary. Presented here are four methods of extracting Dk and Df from dielectric samples of an unknown material and the pros and cons of each.
