| China Electronics Technology Group Corporation No.26 Research Institute 140MHz Low-loss SAW Filter 22MHz Bandwidth Part Number: LB140DS16 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 1dB Bandwidth 3dB Bandwidth 35dB Bandwidth Passband Variation Absolute Delay Ultimate Rejection Subatrate Material Ambient Temperature Package Size C Unit MHz dB MHz MHz MHz dB usec Minimum 139.8 20.8 22 40 Typical 140 12 22 22.8 26.3 0.8 0.93 43 LiNbO3 25 Maximum 140.2 13.5 30.95 1 - dB SMP-53 (13.3 x 6.5 mm Nominal Footprint) 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 L1=L2=78nH C=39pF C1 Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
