| China Electronics Technology Group Corporation No.26 Research Institute 70MHz SAW Filter 2MHz Bandwidth Part Number: LBS70A22 SIPAT Co., Ltd. www.sipatsaw.com Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 35 dB Bandwidth 40 dB Bandwidth 45 dB Bandwidth 50 dB Bandwidth 55 dB Bandwidth Passband Variation Absolute Delay Ultimate Rejection(f02.1MHz) Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz MHz MHz MHz MHz dB usec Minimum 69.95 2.05 50 Typical 70 22.4 1.85 2.12 2.85 2.89 2.97 3.1 3.31 0.8 3.8 53 0.07 25 Maximum 70.05 25 2.15 2.9 3.3 4.1 12.1 1 4 - dB KHz/C C DIP3512 (35.0x12.8x4.7mm3) 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 C1 L1 L2 L1=470nH L2=270nH OUTPUT 50 C2 Notes - Component values may change depending on board layout.
