Notes:
1. All specifications are based on the test circuit shown below
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 manufacturing tolerances
4. Relative to insertion loss at Fo
5. Passband variation is defined as the difference between the lowest loss and the highest loss within the passband. The edge of the
passband is the point where the amplitude begins a downward trend that does not reverse until the stopband
6. This is the optimum impedance in order to achieve the performance shown
