Notes:

1.

All specifications are based on the Qorvo schematics for the reference designs shown on page 4.

2.

In production, devices will be tested 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 the variations due to temperature drift and manufacture tolerances.

4.

Typical values are based on average measurements at room temperature on pcb. (25 °C ±5 °C)
