All 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 temperature drift and manufacturing tolerances
Relative to insertion loss at 330MHz
100% of the 1 dB bandwidth (Maximum peak to adjacent valley)
This is the optimum impedance in order to achieve the performance shown
