Notes:
1. All specifications are based on the TriQuint test circuit matching schematics shown below
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. Referenced to insertion loss at 770 MHz
6. This is the optimum impedance in order to achiev e the performance shown
