| China Electronics Technology Group Corporation No.26 Research Institute 202.5MHz SAW Filter 5MHz Bandwidth Part Number: LBS20201 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 Ultimate Rejection Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz dB usec Minimum 202.4 4.7 5 45 Typical 202.5 23.6 4.8 5.22 6.83 0.6 1.785 52 0.2025 25 Maximum 202.6 25 7 1 3.5 - dB KHz/C C DIP2212 (22.2x12.8x4.7mm3) 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 L1 L2 L1=56+10nH C1=39pF L2=68nH C2=33pF C1 C2 Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
