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
Referenced to the insertion loss at center frequency
Measured as maximum peak to adjacent valley amplitude variation over frequency range.
