Filter Basics 10: Resonators As Microwave Devices

To help customers with filter selection, we generally provide a lot of information on what our filters can do. But in this new Filter Basics Series, we are taking a step back to cover some background information on how filters do what they do. Regardless of the technology behind the filter, there are several key concepts that all filters share that we will dive into throughout this series. By providing this detailed fundamental filter information, we hope to help you simplify your future filtering decisions.

In part 10 of this series, we discuss how resonators function as a microwave device and dive deeper into specifications for ceramic coaxial and dielectric resonators specifically.
