| China Electronics Technology Group Corporation No.26 Research Institute 70MHz SAW Filter 2MHz Bandwidth Part Number: LB070DS04 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 40 dB Bandwidth Passband Variation Absolute Delay Group Delay Variation(f00.7MHz) Phase Linearity(f00.7MHz) Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz dB usec Minimum 69.88 1.3 2 - Typical 70 14.7 1.52 2.05 3.95 0.3 1.51 130 14 -1.26 25 Maximum 70.12 16 4.25 1 340 - nsec deg KHz/C C SMP-53C (13.3x6.5mm 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=180nH C1=100pF C2=33pF Source/Load Impedance=50 ohm C1 C2 Notes - Component values may change depending on board layout.
