• 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 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.

CAUTION: Electrostatic Sensitive Device. 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 Ω test system with

VSWR ≤ 1.2:1. The test fixture L and C are adjusted for minimum insertion loss at the filter center frequency, fc. Note that insertion loss and band-

width and passband shape are dependent on the impedance matching component values and quality.

2. The frequency fc is defined as the midpoint between the 3dB frequencies.

3. Where noted specifications apply over the entire specified operating temperature range of -40 to 90°C.

4. The turnover temperature, TO, is the temperature of maximum (or turnover) frequency, fo. The nominal frequency at any case temperature, Tc, may

be calculated from: f = fo[1 - FTC (To-T

c)2].

5. Frequency aging is the change in fc with time and is specified at +65°C or less. Aging may exceed the specification for prolonged temperat ures

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.

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. Tape and Reel Standard for ANSI / EIA 481.
