A cavity resonator is designed so that a space, or cavity, is enclosed by a metallic conducting surface, like a metal box. Inside the metal box, the electromagnetic waves reflect between the cavity walls.
High Q multilayer ceramic capacitors (MLCCs) are designed and tested to overcome the challenges of developing high-frequency devices that require minimal power loss.
In general, a resonator is an essential component for constructing a bandpass filter since the resonator is what will allow specified frequencies, or bands of frequencies, to pass through the filter.
We explore the basics of lumped element filter design, its characteristics, and how we can push filter design limits to develop a wide variety of high-performance, low-frequency filtering options.
The Knowles Precision Devices DLI brand of technologies now offers a complete range of RF and microwave filtering solutions including custom ceramic filters, resonators, diplexers, and more.
