| China Electronics Technology Group Corporation No.26 Research Institute 140MHz SAW Filter 4.4MHz Bandwidth Part Number: LBT14064 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(f02.2MHz) Phase Linearity(f02.2MHz) VSWR Passband Variation Absolute Delay Ultimate Rejection Subatrate Material Ambient Temperature Package Size Note 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 dB usec Unit MHz dB MHz MHz MHz MHz nsec degree Minimum 139.95 Typical 140 21.5 Maximum 140.05 23 4.4 4.48 5.2 5.4 5.8 120 7 2.1 1 2.29 5.4 6 6.5 200 10 2.3 1.5 2.35 dB 38 40 112LT 25 DIP2712 (27.0x12.8x4.7mm3) Matching Configuration L1 L2 C1 C2 L1=10nH C1=51pF L2=8.2nH C2=82pF Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
