(6) Refer to the Application Information section.

(7) This gain reflects a direct measurement on the PA block by itself. The gain in the signal chain composed by Tx PGA, Tx Filter and PA

equals the Tx PGA gain multiplied by 7 V/V (where 7 V/V is the gain of the PA block when its input is capacitively coupled to the Tx

Filter output). Refer to the Power Amplifier Block section for more information.
