Notes:
1. All specifications are based on the TriQuint schematic for the main reference design shown on page 3
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. Typical values are based on average measurements at room temperature
5. Is defined as the peak to adjacent valley change in amplitude.
6. An external impedance matching network +/- 2% tolerance will be necessary to achieve proposed return loss
7. Relative to 0 dB.
8. This is the optimum impedance in order to achieve the performance shown
