Receiver designs using this filter include superhet with 10.7 MHz or 500 k Hz IF, direct conversion and superregen. Typical applications of these receivers are wireless remote-control and security devices operating in the USA under FCC Part 15. This coupled-resonator filter (CRF) uses selective null placement to provide suppression, typically greater than 40 d B, of the LO and image spurious responses of superhet receivers with 10.7 MHz IF. RFM’s advanced SAW design and fabrication technology is utilized to achieve high performance and very low loss with simple external impedance matching.
