TheAWU6604poweramplifiermoduleisbasedon

ANADIGICS proprietary HELP3™ technology. The

PA is designed to operate up to 17 dBm in the low

powermode,thuseliminatingtheneedforthreegain

state, while still maintaining low quiescent current

andhighefficiencyinlowandmediumpowerlevels.

if the customer chooses to. The directional “daisy

chainable”couplerisintegratedwithinthePAmodule,

therefore there is no need for external couplers.

TheAWU6604 has an integrated voltage regulator,

which eliminates the need for an external constant

voltage source. The PA is turn on/off is controlled
