China Electronics Technology Group Corporation No.26 Research Institute 70MHz SAW Filter 18.7MHz Bandwidth Part Number: LBN7055 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 1dB Bandwidth 3 dB Bandwidth 40 dB Bandwidth 50 dB Bandwidth Passband Variation Absolute Delay Ultimate Rejection(f010MHz) Subatrate Material Ambient Temperature Package Size C Unit MHz dB MHz MHz MHz MHz dB usec Minimum 69.95 Typical 70 27.5 Maximum 70.05 29 18.7 18.9 18.86 19.08 19.85 19.92 0.8 3.67 19.9 20 1 dB 50 55 YZ 25 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=100nH L2=120nH Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
