| China Electronics Technology Group Corporation No.26 Research Institute 140MHz High-Loss SAW Filter 3.5MHz Bandwidth Part Number: LB140DS04 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 35 dB Bandwidth Passband Variation Group delay Variation(80% of 3dB) Ultimate Rejection Absolute Delay Subatrate Material Ambient Temperature Package Size C Unit MHz dB MHz MHz MHz dB nsec dB Minimum 139.8 3.5 4 35 - Typical 140 12 4 4.92 7.9 0.4 60 39 0.86 Maximum 140.2 13.5 8.2 1 100 - usec 112LT 25 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=120nH L3=220nH L2=18nH L4=120nH Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
