When cost, size, and stability are important, look to Knowles Precision Devices’ offering of ceramic resonators.
Knowles Precision Devices offers coaxial resonators spanning applications from 0.3 – 65GHz. Our stable ceramics allow you to achieve high Q, in a small form factor. The high Q obtained in the UHF, VHF, L, S, C bands and microwave frequency range makes these resonators ideal for many applications.
Coaxial resonators can be supplied as quarter wave resonators with one end fully metallized (i.e., shorted), and the other end open, fully metallized on both ends, or as half wave resonators with both ends open.
