Caution! ESD sensitive device.
Exceeding any one or a combination of the Absolute Maximum Rating conditions may
cause permanent damage to the device. Extended application of Absolute Maximum
Rating conditions to the device may reduce device reliability. Specified typical perfor-
mance or functional operation of the device under Absolute Maximum Rating condi-
tions is not implied.

Note: For infrastructure class operation, the maximum allowable current over all operating conditions is 260mA. This implies the need for an
external active bias control network to control I_CC over temperature and normal process variation. A recommended active bias control cir-
cuit is included in the datasheet.
The maximum continuous allowable dissipated power (I_CC*V_CC-P_RF) for this part is 1.3W. For V_CC=5.0V, this implies an I_CC limit of 260mA.
A V_CC of 6.0V would have an I_CC limit of 215mA.
A constant I_CC of 180mA to 220mA provides an excellent combination of high linearity and low power dissipation. Refer to W-CDMA ACP
curves at bottom of datasheet.
