Notes:
1. All specifications are based on the TriQuint schematic for the main reference design.
2. Production test is performed at room temperature to a guard-banded specification to ensure electrical compliance over
temperature.
3. Electrical margin has been built into the design to account for variation due to temperature drift and manufacturing tolerances.
4. Typical values are based on average measure
) unless otherwise noted.
5. This is defined as the difference between the maximum peak to adjacent valley amplitude change within the specified band.

7. This is the optimum impedance in order to achieve the performance shown.

Referenced to 0dB.
This is the optimum impedance in order to achieve the performance shown.
