AEC-Q200 RoHS Compliance This component is compliant with RoHS directive. This component was always RoHS compliant from the first date of manufacture. RF3446E Ideal Front-End Filter for European Wireless Receivers Low-Loss, Coupled-Resonator Quartz Design 433.92 MHz Simple External Impedance Matching SAW Filter The RF3446E is a low-loss, compact, and economical surface-acoustic-wave (SAW) filter designed to provide front-end selectivity in 433.92 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.

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 and passband shape are dependent on c the impedance matching component values and quality. 2. The frequency f is defined as the midpoint between the 3dB frequencies. c 3. Where noted specifications apply over the entire specified operating temperature range of -40C to +90C. 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 +65C. 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.
