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.
