All specifications are based on the TriQuint test circuit shown on page 6
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
Typical values are based on average measurements at room temperature
Relative to zero dB
This is the optimum impedance in order to achieve the performance shown
