| China Electronics Technology Group Corporation No.26 Research Institute 70MHz SAW Filter 20.4MHz Bandwidth Part Number: LBN7044 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 3 dB Bandwidth 45 dB Bandwidth Passband Variation Absolute Delay Ultimate Rejection Subatrate Material Ambient Temperature Package Size C Unit MHz dB MHz MHz dB usec Minimum 69.9 Typical 70 25 Maximum 70.1 26 20.4 20.6 22.12 1 2.4 22.2 1.5 dB 50 52 128-LiNbO3 25 DIP2212 (22.7x12.7x5.2mm3) 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 L1L2270nH L3330nH Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
