China Electronics Technology Group Corporation No.26 Research Institute 138.625MHz SAW Filter 0.50MHz Bandwidth Part Number: LBS13807 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 Phase Linearity Group Delay Variation Ultimate Rejection f02.5MHz f020MHz Subatrate Material Ambient Temperature Package Size C dB dB 37 40 41 45 Quartz 25 SF26 - Unit MHz dB MHz MHz MHz dB usec Minimum 138.585 0.5 - Typical 138.625 9.5 0.53 0.86 1.98 0.3 1.88 1.8 80 Maximum 138.665 11 2.10 0.6 - deg nsec 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 L3=33nH L2=56nH C1=47pF Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
