| 433.92 MHz SAW Filter * * * * Designed to Provide Front-end Selectivity in 433.92 MHz Low-Loss, Coupled-Resonator Quartz Design Simple External Impedance Matching Ultra Miniature Ceramic QCC8C SMD Package SF5508 Absolute Maximum Rating (Ta=25C) Parameter Input Power Level DC Voltage VDC Between Any Two Pins Operating Temperature Range Storage Temperature Range Pin VDC Rating 10 12 -10 ~ +60 -40 ~ +85 Unit dBm V C C TA Tstg Electronic Characteristics Parameter Nominal Frequency (at 25C) (Center frequency between 3dB point) Insertion Loss Attenuation 3dB Passband Passband Ripple At fC - 21.4 MHz (Image) Rejection At fC - 10.7 MHz (LO) Ultimate Operating Temperature Range Temperature Stability Turnover Temperature Turnover Frequency Frequency Temperature Coefficient Frequency Aging Absolute Value during the First Year Sym fC Minimum NS 40 20 -10 25 1.0 Typical 433.92 3.5 600 50 30 60 fC 0.032 Maximum NS 5.5 900 1.0 +60 55 10 Unit MHz dB KHz dB dB dB dB C C MHz ppm/C 2 IL BW3 TC TO fO FTC |fA| - ppm/yr M DC Insulation Resistance Between any Two Pins NS = Not Specified Notes: 1. The frequency fC is defined as the midpoint between the 3dB frequencies. Unless noted otherwise, all measurements are made with the filter installed in the specified test fixture that 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, fC. Note that insertion loss, bandwidth, and passband shape are dependent on the impedance matching component values and quality. Unless noted otherwise, specifications apply over the entire specified operating temperature range. 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 in subsequent years. 5. Turnover temperature, T0, is the temperature of maximum (or turnover) frequency, f0. The nominal frequency at any case temperature, TC, may be calculated from: f = f0 [1 - FTC (T0 - TC)2]. The specifications of this device are based on the test circuit shown above and subject to change or obsolescence without notice. All equipment designs utilizing this product must be approved by the appropriate government agency prior to manufacture or sale. Our liability is only assumed for the Surface Acoustic Wave (SAW) component(s) per se, not for applications, processes and circuits implemented within components or assemblies.
