use time. ꢀꢂe AWꢀ6751 is designed for use botꢂ

witꢂ and witꢂout average power tracking (APꢀ). APꢀ

can be used to optimize tꢂe V^CClevel for tꢂe desired

output power level and linearity, wꢂicꢂ greatly reduces

tꢂe total current drawn from tꢂe battery. ꢀꢂis feature,

in conjunction witꢂ hPM and LPM operating modes,

enables signiﬁcant improvements in overall power

added efﬁciency of tꢂe AWꢀ6751 across tꢂe entire

dynamic range of operating powers. APꢀ requires

use of an external variable voltage supply (DC-DC

converter), wꢂicꢂ is used to provide tꢂe variable

voltage to V^CCpad of tꢂe ampliﬁer. In some cases, tꢂe

average current over tꢂe ꢀꢁ.09 power proﬁle can be

reduced by more tꢂan 25%. A low-leakage sꢂutdown

mode increases standby time.

FEATURES

•

WCDMA Compliant

Internal Voltage Regulator

Integrated “daisy cꢂainable” directional coupler

witꢂ CPL^INand CPLOUꢀ port

ꢀꢂe AWꢀ6751 ꢂas built-in daisy-cꢂainable RF

couplers for eacꢂ band, wꢂicꢂ provide ꢂigꢂ directivity

and 20 dB coupling. ꢀꢂe AWꢀ6751 also incorporates

matcꢂing networks optimized for output power,

efﬁciency and linearity in a 50 Ω system. ꢀꢂe device

is designed for use in systems wꢂere a single RF

input may be switcꢂed to drive band 1 and 8 antenna

outputs. AWꢀ6751 is manufactured on an advanced

InGaP hBꢀ MMIC tecꢂnology offering state-of-tꢂe-art

reliability, temperature stability, and ruggedness.
