| China Electronics Technology Group Corporation No.26 Research Institute 385MHz SAW Filter 30MHz Bandwidth Part Number: LB385DS01 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 35 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 385 13.5 Maximum 15 30 33.55 35.3 42.1 0.7 62 1 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 C1 C2 L1=18nH C1=10pF L2=15nH C2=10pF Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
