All specifications are based on the Qorvo schematic for the main reference design. 5. Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances. 6. Typical values are based on average measurements of 12 devices at room temperature. 7. This is defined as the worst difference between a peak and adjacent valley within defined frequency points. 8. Relative to zero dB. 9. This is the optimum impedance in order to achieve the performance shown. Datasheet, December 4, 2018 Subject to change without notice 2 of 15 www.qorvo.com
