| China Electronics Technology Group Corporation No.26 Research Institute 74MHz SAW Filter 4MHz Bandwidth Part Number: LBS07405 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 30 dB Bandwidth 40 dB Bandwidth Passband Variation Absolute Delay Group Delay Variation(f01.8MHz) Ultimate Rejection(Outside f03MHz) Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz MHz dB usec Minimum 73.92 3.7 45 Typical 74 27.4 3.72 3.95 4.45 4.51 0.7 4.48 100 50 0.074 25 Maximum 74.08 29 4.5 5 0.9 300 - nsec 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 C1 L1 L2 L1=280nH L2=270nH OUTPUT 50 C2 Notes - Component values may change depending on board layout.
