5.
All specifications are based on the TriQuint schematic shown on page 3
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.
All attenuation measurements are measured relative to minimum insertion loss.
This is the optimum impedance in order to achieve the performance shown.
