All specifications are based on the TriQuint schematic reference design shown on page 3.
In production, devices will be tested at room temperature to a guard-banded 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.
Total variation over the defined frequency range
Absolute attenuation measurements are referenced to zero dB.
This is the optimum impedance in order to achieve the performance shown
