Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 40 dB Bandwidth 50 dB Bandwidth Passband Variation Absolute Delay Group Delay Variation(f03MHz) Ultimate Rejection Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz MHz dB usec Minimum 139.85 5.44 6 50 Typical 140 23 5.76 6.22 7.97 8.15 0.8 1.58 70 55 -2.52 25 SMD13.3*6.5 Maximum 140.15 25 8.34 0.9 90 - nsec 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 L1 L2 L1=56nH L2=82nH C1=C2=18pF C1 Source/Load Impedance=50 ohm C2 Notes - Component values may change depending on board layout.
