Data presented in the figures on the following pages are based on typical operating conditions at +25°C, AVDD18 = 1.8V, AVDD33 =

3.3V, and DVDD18 = 1.8V, unless otherwise specified.

Conditions:

Waveforms: WCDMA 2-carrier 6.5dB PAR and LTE 10MHz 7.5dB PAR

A/DVDD18 = 1.7V/1.9V, AVDD33 = 3.1V/3.5V
