Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 30 dB Bandwidth Passband Variation Absolute Delay Phase Linearity(f012.5MHz) Group Delay Variation(f012.5MHz) Ultimate Rejection Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz dB usec deg Minimum 69.8 25 27.3 35 Typical 70 26.9 25.5 27.5 33.5 0.6 0.816 5 20 38 -5.74 25 Maximum 70.2 28 27 29.8 35 1 20 70 - nsec dB KHz/C C DIP2212 (22.7x12.7x5.2mm3) 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=150nH L2=100nH Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
