RF3336E

RF3336E Front-End Filter for European Wireless Receivers Low-Loss, Coupled-resonator Quartz Design Simple External Impedance Matching Complies with Directive 2002/95/EC (RoHS) Pb 868.35 MHz SAW Filter The RF3336E is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide front-end selectivity in 868.35 MHz receivers. Receivers using this filter include superheterodynes with 10.7 MHz or 500 kHz IFs, direct conversion receivers and superregenerative receivers. Typical applications of these receivers include 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 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.
