Notes:
1. All specifications are based o n the TriQuint test circuit shown on page 4
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. Variation is defined as the total peak to peak variation over the defined frequency range
6. Relative to insertion loss at Center Frequency
7. This is the optimum impedance in order to achiev e the performance shown
