| China Electronics Technology Group Corporation No.26 Research Institute 70MHz SAW Filter 25.58MHz Bandwidth Part Number: LBN7049 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 3 dB Bandwidth 20 dB Bandwidth 30 dB Bandwidth 40 dB Bandwidth Passband Variation Absolute Delay Ultimate Rejection Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz MHz dB usec Minimum 69.95 25.58 50 Typical 70 26 26.03 27.57 28.06 28.31 0.6 1.9482 54 -5.74 25 Maximum 70.05 28 28.5 1.2 - 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 L1=L2=82nH L3=180nH Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
