RF1432C • Ideal Front-End Filter for European Wireless Receivers • Low-Loss, Coupled-Resonator Quartz Design 319.500 MHz • Simple External Impedance Matching • Complies with Directive 2002/95/EC (RoHS) Pb SAW Filter The RF1432C is a low-loss, compact and economical surface-acoustic-wave (SAW) filter designed to provide front-end selectivity in 319.500MHz receivers. Recevier designs using this filter include superhet with 10.7MHz or 500kHz IF, direct conversion and superregen. This coupled-resonator filter (CRF) uses selective null placement to provide suppression, typically greater than 40dB, of the LO and image spurious responses of superhet receivers with 10.7MHz IF. Murata’s advanced SAW design and fabrication technology is utilized to achieve high performance and very low loss with simple external impedance matching (not included). Quartz construction provides excellent frequency stability over a wide temperature range.

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 . Note that insertion loss, bandwidth, and passband shape c 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. 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 calculated from: f=f [1-FTC(T -T)2]. o o c 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 without notice. 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. ©C2o0p1y0r-i2g0h1t5 ©by M Muurraattaa E Mleactnrounfiaccs tNu.rAin., gIn Cc.o., Ltd.
