| China Electronics Technology Group Corporation No.26 Research Institute 72MHz SAW Filter 0.3MHz Bandwidth Part Number: LBS07203 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 40 dB Bandwidth 50 dB Bandwidth Passband Variation(f00.075MHz) Absolute Delay Ultimate Rejection Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz MHz dB usec Minimum 71.95 0.3 40 Typical 72 9 0.24 0.4 1.11 1.18 0.1 2.37 52 0.072 25 Maximum 72.05 12.5 1.3 1 - dB KHz/C C DIP2012 (20x12.5x4mm3) 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 INPUT 50 C1 L1 L2 L1=L2=220nH OUTPUT 50 C2 Notes - Component values may change depending on board layout.
