Notes:

1.

All specifications are based on the TriQuint schematic for the main reference design 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.

Relative to zero dB

6.

All power levels are referenced to the Downlink to Antenna port.

7.

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