China Electronics Technology Group Corporation No.26 Research Institute 127MHz SAW Filter MHz Bandwidth Part Number: LBT12701 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 3 dB Bandwidth 18 dB 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 126.92 6 50 Typical 127 24.4 6.03 6.54 6.8 6.86 1.1 3.685 53 -2.286 25 Maximum 127.08 27 6.6 7 7.4 1.5 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=22nH L2=33nH Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
