| China Electronics Technology Group Corporation No.26 Research Institute 199MHz SAW Filter 6MHz Bandwidth Part Number: LBS19902 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 50 dB Bandwidth Passband Variation Absolute Delay Ultimate Rejection Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz dB usec Minimum 198.85 6 45 Typical 199 25.5 5.6 6.1 8.08 0.4 2.0685 50 0.199 25 Maximum 199.15 27 8.2 0.8 - 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 L1 L2 L1=68nH C1=15pF L2=56nH C2=22pF C1 C2 Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
