Specifications Parameter Center Frequency Insertion Loss 1 dB Bandwidth 3 dB Bandwidth 40 dB Bandwidth 50 dB Bandwidth Passband Variation Absolute Delay f01.45MHz f01.65MHz Ultimate Rejection f02.05MHz f06.05MHz f015MHz Material Temperature coefficient Ambient Temperature Package Size Unit MHz dB MHz MHz MHz MHz dB usec Minimum 121.7 2 35 45 50 55 55 Typical 121.8 23.8 1.96 2.13 2.84 2.92 0.3 3.93 51 55 58 60 60 0.122 25 Maximum 121.9 26 1.2 4 - dB dB dB dB 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 OUTPUT 50 L1=82nH L2=68nH C1=39pF Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
