.. ® RF1295C 451.35 MHz SAW Filter - - - - Ideal Front-End Filter for 451.35 MHz Wireless Receivers Low-Loss Coupled-Resonator Quartz Design Simple External Impedance Matching Pb plies with Directive 2002/95/EC (Ro HS) The RF1295C is a low-loss, pact, and economical surface acoustic wave (SAW) filter designed to provide front-end selectivity in 451.35 MHz receivers. Recevier 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 Europe under ETSI I-ETS 300 220. 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 (not included).
