| China Electronics Technology Group Corporation No.26 Research Institute 240MHz SAW Filter 30MHz Bandwidth Part Number: LB240DS01 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 40 dB Bandwidth Passband Variation Ultimate Rejection(f035MHz) Group Delay Variation Subatrate Material Ambient Temperature Package Size C Unit MHz dB MHz MHz MHz dB Minimum Typical 240 15.1 Maximum 16 30 32.15 34.34 44.54 0.9 65 2 dB nsec 35 38 60 YZ 25 SMD0705A (7x5x1.6mm3) 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=27+27nH C1 C2 L2=22+18nH C1=15pF C2=18pF Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
