RF1396C Ideal Front-End Filter for European Wireless Receivers Pb Low-Loss, Coupled-Resonator Quartz Design 434.42 MHz Simple External Impedance Matching Complies with Directive 2002/95/EC (RoHS) SAW Filter The RF1396C is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide front-end selectivity in 434.420 MHz receivers. Receiver designs using this filter include superheterodynes with 10.7 MHz or 500 kHz IF, direct conversions and super- regeneratives. 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 dB, of the LO and image spurious responses of superhet receivers with 10.7 MHz IF. Muratas advanced SAW design and fabrication technology is utilized to achieve high performance and very low loss with simple external impedance matching.

Observe precautions for handling. NOTES: 1. Unless noted otherwise, all measurements are made with the filter installed in the specified test fixture which is connected to a 50 test system with VSWR 1.2:1. The test fixture L and C are adjusted for minimum insertion loss at the filter center frequency, f . Note that insertion loss and bandwidth and passband c shape are dependent on the impedance matching component values and quality. 2. The frequency f is defined as the midpoint between the 3dB frequencies. c 3. Where noted specifications apply over the entire specified operating temperature range. 4. The turnover temperature, T , is the temperature of maximum (or turnover) frequency, f . The nominal frequency at any case temperature, T , may be O o c 2 calculated from: f = f 1 - FTC (T -T ) . o o c 5. Frequency aging is the change in fc with time and is specified at +65C or less. Aging may exceed the specification for prolonged temperatures above +65C. Typically, aging is greatest the first year after manufacture, decreasing significantly in subsequent years. 6. The design, manufacturing process, and specifications of this device are subject to change without notice. 7. One or more of the following U.S. Patents apply: 4,54,488, 4,616,197, and others pending. 8. All equipment designs utilizing this product must be approved by the appropriate government agency prior to manufacture or sale. 2010-2015 by Murata Electronics N.A., Inc.
