Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 35 dB Bandwidth 40 dB Bandwidth 45 dB Bandwidth 50 dB Bandwidth 55 dB Bandwidth Passband Variation Absolute Delay Ultimate Rejection(f015MHz) Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz MHz MHz MHz MHz dB usec Minimum 87.9 6.25 60 Typical 88 31 6.32 6.47 7.01 7.04 7.06 7.1 7.17 0.6 4.5 63 -1.58 25 Maximum 88.1 33 7.1 7.4 8.2 16.2 1.0 4.5 - 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 L2 L1=82nH OUTPUT 50 C2 L2=100nH C2=56pF C1=82pF Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
