| China Electronics Technology Group Corporation No.26 Research Institute 70MHz SAW Filter 1MHz Bandwidth Part Number: LBS70A25 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 25 dB Bandwidth 35 dB Bandwidth 40 dB Bandwidth 45 dB Bandwidth 50 dB Bandwidth Passband Variation Absolute Delay Ultimate Rejection Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz MHz MHz MHz MHz dB usec Minimum 69.95 1.3 55 Typical 70 23.3 1.16 1.39 2.03 2.15 2.2 2.23 2.34 0.3 3.34 58 0.07 25 Maximum 70.05 25 1.4 2.1 2.5 3.3 11.3 1.2 4 - dB KHz/C C DIP2712 (27.0x12.8x4.7mm3) 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 L1 L2 L1=L2=180nH OUTPUT 50 Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
