This manual introduces the CERAFIL® ceramic filter family, describing its piezoelectric operating principle, key features, and typical applications such as stereo systems, TV sets, and automotive radios. It also defines technical terminology, impedance matching, and design considerations for high‑selectivity IF circuits.
The document provides detailed sections on filter types, discriminators, traps, and practical usage instructions, along with frequency‑characteristic tables and application examples to help engineers integrate the filters into their designs.
