China Electronics Technology Group Corporation No.26 Research Institute 140MHz SAW Filter 9.4MHz Bandwidth Part Number: LBT14065 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 1.5 dB Bandwidth 25 dB Bandwidth 30 dB Bandwidth 40 dB Bandwidth Group delay Variation(f0±3.76MHz) Phase Linearity(f0±3.76MHz) Passband Variation Absolute Delay VSWR Ultimate Rejection Subatrate Material Ambient Temperature Package Size 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 °C Unit MHz dB MHz MHz MHz MHz nsec degree dB usec Minimum 139.95 Typical 140 21.7 Maximum 140.05 23.2 9.4 9.45 10.3 10.4 10.8 100 6 1.1 2.28 1.6 10.4 11 11.5 130 10 1.5 2.3 2.3 dB 37 40 112LT 25 DIP2712 (27.0x12.8x4.7mm3) Matching Configuration L1 L2 L1=22nH C1 C2 L2=56nH C2=33pF C1=51pF Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
