Understanding Ceramic Coaxial Resonator Filters

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.

Understanding Suspended Substrate Stripline Filters

Suspended substrate stripline filter technology offers many advantages for designers looking for wide passbands, deep rejection and sharp roll-off in the transition. By utilizing air cavities instead of dielectric materials used in traditional stripline fabrications, these filters achieve better Q and better thermal stability, making them suitable for many high-performance applications in a wide range of operating conditions. This practical overview explains everything you need to know about Mini-Circuits’ line of suspended substrate filters and multiplexers.
