Electrical Characteristics

• Ideal Front-End Filter for European Wireless Receivers

• Low-Loss, Coupled-Resonator Quartz Design

• Simple External Impedance Matching

• Complies with Directive 2002/95/EC (RoHS)

The RF3319D is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide

front-end selectivity in 868.95 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 operating in Europe under ETSI I-ETS 300 220, in Germany

under FTZ 17 TR 2100, in the United Kingdom under DTI MPT 1340 (for automotive only), in France under

PTT Specifications ST/PAA/TPA/AGH/1542, and in Scandinavia.

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 (not included).

The turnover temperature, T

be calculated from: f = f

Frequency aging is the change in fc with time and is specified at +65°C 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.
