| China Electronics Technology Group Corporation No.26 Research Institute 70MHz Low-loss SAW Filter 0.5MHz Bandwidth Part Number: LBS7002L www.sipatsaw.com SIPAT Co., Ltd. Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 35 dB Bandwidth Passband Variation Absolute Delay Ultimate Rejection Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz dB usec Minimum 69.95 0.35 0.5 40 Typical 70 9 0.39 0.6 1.398 0.1 2.4 45 0.07 25 SMD19.0*6.5B Maximum 70.05 10 1.4 1 - dB KHz/C C 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=(330+68)nH L2 OUTPUT 50 C2 L2=(470+33)nH C1=C2=100pF Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
