handset. The device has mode-switching to take

advantage of its high efficiency operation over a wide

range of output powers. Higher low power efficiency

is achieved without an external DAC or DC-DC

converter. The integrated power amplifier module

employs a proprietary bias control and temperature

compensation circuit that assures stable operation,

even at extreme temperature conditions.

The self contained 4 x 4 x 1.5 mm surface mount

package incorporates matching networks optimized

for output power, efficiency and linearity in a 50

PRODUCT DESCRIPTION

The AWT6137 CDMA/AMPS Power Amplifier is a high

performance CDMA2000/ 1XRTT amplifier designed

specifically for Cellular wireless applications. This

rugged, easy to use InGaP HBT design delivers

state of the art efficiency and temperature stability

with very low DC power consumption. The

AWT6137 PA module has the lowest CDG currents

available to handset manufacturers today.

A combination of low idle current and mode

switching enables the AWT6137 to deliver

unparalleled CDMA average power efficiencies.

This bias feature allows the AWT6137 to significantly

increase the battery usage time of a mobile
