• 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 RF1411D is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide

front-end selectivity in 869.2625 MHz receivers. Receiver designs using this filter include superhet 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).

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, f

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

2.

3.

Where noted, specifications apply over the entire specified operating temperature range of -45°C to +85°C.

4.

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.

5.

The design, manufacturing process, and specifications of this device are subject to change.

6.

One or more of the following U.S. Patents apply: 4,54,488, 4,616,197, and others pending.

7.

All equipment designs utilizing this product must be approved by the appropriate government agency prior to manufacture or sale.

8.

Tape and reel standard per ANSI / EIA 481.
