Ceramic resonator filters boast impressive Q-factor and relative permittivity, allowing a unique combination of low passband insertion loss with minimal ripple, very steep roll-off and deep rejection floor on the order of 80 to 100 dB, all in a small, surface-mountable device. They’re ideal solutions for many sensitive applications in crowded spectral environments where size is a critical requirement. Read on to learn more about the characteristics and advantages of these useful filters as well as Mini-Circuits’ industry-leading design and manufacturing capabilities.
