| China Electronics Technology Group Corporation No.26 Research Institute 143.625MHz SAW Filter 0.5MHz Bandwidth Part Number: LBS14302 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 1dB bandwidth 40dB bandwidth Ultimate Rejection f02.5MHz f020MHz Passband Variation Absolute Delay Subatrate Material Ambient Temperature Package Size C dB usec Unit MHz dB MHz MHz dB Minimum 143.55 Typical 143.625 13.6 Maximum 143.7 16 0.5 0.57 2 2.1 37 40 40 45 0.5 1.71 Quartz 25 SF-26 0.8 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=82nH L2=82nH Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
