All specifications are based on the Qorvo schematics for the reference designs shown on page 5. 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. 5. This is the optimum impedance in order to achieve the performance shown. DATA SHEET: September 2016 Rev.
