Shutdown Mode

The power amplifier may be placed in a shutdown

mode by applying logic low levels (see Operating

Rangestable)totheVENABLE and VMODE1voltages.

Bias Modes

ThepoweramplifiermaybeplacedineitheraLowBias

mode or a High Bias mode by applying the appropriate

logic level (see Operating Ranges table) to VMODE1.

The Bias Control table lists the recommended modes

of operation for various applications. VMODE2 is not

necessary for this PA.

Two operating modes are available to optimize

current consumption. High Bias/High Power operating

mode is for POUTlevels> 15 dBm. At around 16 dBm

outputpower,thePAshouldbe“ModeSwitched”to

Medium/Lowpowermodeforlowestquiescentcurrent
