RF1400D Ideal Front-End Filter for European Wireless Receivers Pb Low-Loss, Coupled-Resonator Quartz Design Simple External Impedance Matching 433.92 MHz Wide Bandwidth for Multi-Channel Receiver Application Complies with Directive 2002/95/EC (RoHS) SAW Filter The RF1400D 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. Wider bandwidth for channelized receiver applications. 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. Muratas advanced SAW design and fabrication technology is utilized to achieve SM3838-8 Case high performance and very low loss with simple external impedance matching. 3.8 x 3.8 Characteristic Sym Notes Minimum Typical Maximum Units f 1, 2, 3 Center Frequency at 25C Absolute Frequency c 433.92 MHz Insertion Loss IL 1, 3 2.0 3.0 dB BW 1, 2, 3 kHz 3 dB Bandwidth 1000 1150 3 Rejection 10 - 414 MHz 40 50 414 - 425 MHz 30 40 426 - 432 MHz 16 20 1, 3 dB 435 - 442 MHz 10 15 442 - 550 MHz 26 30 550 - 1000 MHz 45 50 2 Frequency Temperature Coefficient FTC 0.032 ppm/C Frequency Aging Absolute Value during the First Year fA 5 10 ppm/yr Input Z = R llC Z Impedance fc IN IN IN IN 279 ll 4.1pf 1 Output Z = R llC Z 279 ll 4.1pf OUT OUT OUT OUT Lid Symbolization (Y=year WW=week D=day of week) 490 // YWWS Standard Reel Quantity Reel Size 7 Inch 500 Pieces/Reel 9 Reel Size 13 Inch 3000 Pieces/Reel 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 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 c shape are dependent on 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 +105C. 4. The turnover temperature, T , is the temperature of maximum (or turnover) frequency, f . The nominal frequency at any case temperature, T , may be O o c 2 calculated from: 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. All equipment designs utilizing this product must be approved by the appropriate government agency prior to manufacture or sale. 9.
