| China Electronics Technology Group Corporation No.26 Research Institute 129.2MHz SAW Filter 6MHz Bandwidth Part Number: LBT12902 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 35 dB Bandwidth 40 dB Bandwidth 45 dB Bandwidth 50 dB Bandwidth 55 dB Bandwidth Passband Variation Absolute Delay Ultimate Rejection(f015MHz) Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz MHz MHz MHz MHz dB usec Minimum 129.1 6.15 60 Typical 129.2 27 5.96 6.19 6.91 6.95 6.99 7.02 7.1 1 3.85 70 -2.33 25 Maximum 129.3 28 7 7.4 8.2 16.2 1.5 4 - dB KHz/C C DIP3512 (35.2x12.7x5.2mm3) Notes: 1. All specifications are based on the test circuit shown 2. In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over temperature 3. Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances 4. This is the optimum impedance in order to achieve the performance show Matching Configuration INPUT 50 C1 L1 L2 L1=39nH OUTPUT 50 C2 L2=47nH C2=36pF C1=47pF Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
