China Electronics Technology Group Corporation No.26 Research Institute 175.75MHz SAW Filter 1.5MHz Bandwidth Part Number: LBS17501 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 45 dB Bandwidth Passband Variation Absolute Delay Ultimate Rejection Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz dB usec Minimum 175.67 1.5 50 Typical 175.75 25 1.28 1.55 2.78 0.6 2.87 53 0.1757 25 Maximum 175.83 27 2.8 0.9 - dB KHz/C C DIP2712 (27.0x12.8x4.7mm3) 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 Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
