| China Electronics Technology Group Corporation No.26 Research Institute 78.8MHz SAW Filter 10MHz Bandwidth Part Number: LBN07904 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 1.5 dB Bandwidth 3 dB Bandwidth 35 dB Bandwidth 40 dB Bandwidth 45 dB Bandwidth 50 dB Bandwidth 55 dB Bandwidth Passband Variation Absolute Delay Ultimate Rejection(f015MHz) Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz MHz MHz MHz MHz dB usec Minimum 78.7 10 55 Typical 78.8 27.3 10.05 10.17 10.73 10.77 10.8 10.83 10.86 0.9 4.38 59 -7.41 25 Maximum 78.9 28 10.8 11.2 12 20 1.5 4.5 - dB KHz/C C DIP3512 (35.0x12.8x4.7mm3) 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 INPUT 50 L1 L1=10nH L2 OUTPUT 50 C1 L2=120nH C1=22pF Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
