Notes:
1. All specifications are based on the TriQuint schematic 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, unless otherwise noted
5. Referenced to maximum insertion loss within the specified frequency points
6. Relative to insertion loss at center frequency
7. Total variation over the defined frequency range.
8. Absolute Attenuation measurements are referenced to zero dB
9. This is the optimum impedance in order to achieve the performance shown
