RF/Microwave Filters Serve Communication Needs

Filters play a crucial role in any system. This collection of articles addresses the topic of filters from various angles.

High-frequency filters are critical components in enabling the wireless communication we all depend on. Filters are also needed for more than just the commercial wireless market—for example, military and satellite-communication (satcom) applications rely on them as well. With that in mind, we have collected several articles on different aspects of filters that we hope you will enjoy.


New Resonator Technology Targets Next-Generation Filters

The market for RF filters targeted at mobile communications has grown significantly over the last several years. And with 5G coming, that demand is expected to rise. “The highest-growth element in an RF front end (RFFE) is the filter.”
