RF3355C

Preliminary ® RF3355C Pb Ideal Front-End Filter for Wireless Receivers Low-Loss, Coupled-Resonator Quartz Design Simple External Impedance Matching Complies with Directive 2002/95/EC (RoHS) The RF3355C is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide front-end selectivity in 390 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. 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. 390.0 MHz SAW Filter SM5050-8 Case 5x5 Electrical Characteristics Characteristic Center Frequency at 25°C Tolerance from 390.0 MHz Minimum Insertion Loss 389.82 -390.22 MHz Passband (relative to ILmin) Passband (relative to ILmin) Attenuation: (relative to IL min) 0 - 345 MHz 345 - 370 MHz 370 - 388.94 MHz 391.5 - 410 MHz 410 - 475 MHz 475 - 1000 MHz Impedance at FC ; Input ZIN=RIN//CIN Output ZOUT=ROUT//COUT Turnover To Frequency Aging Absolute Value During the First Year Reel Size 7 Inch Reel Size 13 Inch Lid Symbolization (in addition to Lot and/or Date Codes) Standard Reel Quanti...
