Note: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These
are stress ratings only and functional operation of the device at or beyond these ratings in the operational sections of
the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability. The Power Amplifier may be damaged if switched on without proper load or termination connected.
TX matching network design will influence TX V_RF-peak on TX output pin. Caution: ESD sensitive device.
