Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 40 dB Bandwidth 50 dB Bandwidth Passband Variation Absolute Delay (f05.3MHz) (f05.5MHz) Ultimate Rejection (f05.9MHz) (f09.9MHz) Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz MHz dB usec Minimum 139.85 9.75 35 45 50 55 Typical 140 28.1 9.55 9.8 10.6 10.7 0.9 3.93 51 52 53 56 -13.16 25 Maximum 140.15 29 1.5 4 - dB dB dB dB KHz/C C DIP3512 (35.2x12.7x5.2mm3) 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 L1=L2=33nH L2 OUTPUT 50 C2 Notes - Component values may change depending on board layout.
