PRODUCT DESCRIPTION
The AWT6244 HELP3
TM
PA is a next generation
product for TD-SCDMA handsets. This PA incorporates
ANADIGICS’ HELP3
TM
technology to provide low
power consumption without the need for an external
voltage regulator or DC/DC Converter. The AWT6244
is manufactured on an advanced InGaP HBT
MMIC technology offering state-of-the-art reliability,
temperature stability, and ruggedness. There are two
operating modes for optimum efficiency at high and
medium/low power output levels with a single mode
input. A shutdown mode with low leakage current
increases handset talk and standby-time. The self-
contained 3 mm x 3 mm x 1 mm surface mount
package incorporates matching networks optimized
for output power, efficiency, and linearity in a 50
Ω
system.
