| China Electronics Technology Group Corporation No.26 Research Institute 198.5MHz SAW Filter 5MHz Bandwidth Part Number: LBS19801 www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 30 dB Bandwidth 40 dB Bandwidth 50 dB Bandwidth Passband Variation Absolute Delay Ultimate Rejection Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz MHz MHz dB usec Minimum 198.42 4.8 5 50 Typical 198.5 27 4.84 5.04 5.63 5.72 5.93 0.7 3.96 51 0.1985 25 Maximum 198.58 28 5.7 5.9 6.2 0.9 4 - 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 L1=47nH L2 OUTPUT 50 C2 L2=33nH C1=C2=33pF Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
