简  介: RF1171D 418.0 MHz SAW Filter Ideal Front-End Filter for Wireless Receiver in the US and UK Low-Loss, Coupled-Resonator Quartz Design Surface-Mount Ceramic Case with 50 mm2 Footprint Simple External Impedance Matching Complies with Directive 2002/95/EC (RoHS) Pb The RF1171D is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide front-end selectivity in 418.0 MHz receivers. Receiver designs using this filter include superhet with 10.7 MHz or 500 kHz 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 dB, 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.
