Notes:
1. All specifications are based on the TriQuint matching schematics shown on page 5
2. In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over
temperature
3. Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances
4. Relative to insertion loss at center frequency
5. Typical values are based on average measurements at room temperature
6. This is the optimum impedance in order to achieve the performance shown
Subject to change or obsolescence without notice
