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
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 Ω
system making it easy to incorporate the device into
BOTH new and existing designs.[em11][em11][em11]
