• Ideal Front-End Filter for European Wireless Receivers

• Low-Loss, Coupled-Resonator Quartz Design

• Simple External Impedance Matching

The RF3391D is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide

front-end selectivity in 433.42 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.

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 ≤

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

2.

3.

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

4.

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 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.

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 Per ANSI / EIA 481.

10.

This product complies with Directive 2002/95/EC of the European Parlament and of the Council of 27 January 2003 on the restriction of the use of certain

hazadous substances in electrical and electronic equipment.
