RF3319E Ideal Front-End Filter for European Wireless Receivers Low-Loss, Coupled-Resonator Quartz Design Simple External Impedance Matching 868.95 MHz Complies with Directive 2002/95/EC (RoHS) Pb SAW Filter The RF3319E is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to pro- vide front-end selectivity in 868.95 MHz receivers. Receiver designs using this filter include superheterodyne receivers with 10.7 MHz or lower intermediate frequencies, plus direct conversion and superregenerative receivers. Typical applications of these receivers are wireless remote-control and security devices operating in Europe under ETSI I-ETS 300 220 regulations.

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 are dependent on the impedance c matching component values and quality. 2. The frequency f is defined as the midpoint between the 3 dB frequencies. c 3. Where noted, specifications apply over the entire specified operating temperature range of -40 to 90 C. 4. The turnover temperature, T , is the temperature of maximum (or turnover) frequency, f . The nominal frequency at any case temperature, T , may be calculated from: O o c 2 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 +65 C. 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. 9.
