China Electronics Technology Group Corporation No.26 Research Institute 120MHz SAW Filter 7MHz Bandwidth Part Number:LBT12021 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 30dB Bandwidth 40 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 dB usec Minimum 120.42 7 45 Typical 120.5 26.3 7.03 7.93 8.03 8.13 0.7 3.83 46 -2.16 25 Maximum 120.58 28 8 8.4 9 0.9 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 L1 L2 L1=39nH C1=82pF L2=56nH C2=47pF Source/Load Impedance=50 ohm C1 C2 Notes - Component values may change depending on board layout.
