All target specifications are based on the test circuit shown below
In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over
temperature
Electrical margin has been built into the design to account for the variations due to manufacturing tolerances
Relative to insertion loss at 183.6 MHz
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
This is the optimum impedance in order to achieve the performance shown
