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.
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.
Lumped element filters offer small size at low frequencies that are not achievable with common ceramic, cavity, or waveguide implementations. These filter designs can be developed for 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.
