Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 40 dB Bandwidth 50 dB Bandwidth Passband Variation Absolute Delay Phase Linearity(f02.3MHz) Group Delay Variation(f02.3MHz) Ultimate Rejection Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz MHz dB usec deg Minimum 69.91 4.5 5 50 Typical 70 22.8 4.78 5.26 7.13 7.31 0.5 3 3 50 58 -1.26 25 Maximum 70.09 26 7.5 0.8 6 100 - nsec dB KHz/C C DIP2212 (22.2x12.8x4.7mm3) 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=L2=180nH L2 OUTPUT 50 C2 Notes - Component values may change depending on board layout.
