Dual Band WCDMA Wireless Handsets
Dual Mode 3GPP Wireless Handsets
PRODUCT DESCRIPTION
The AWT6276 meets the increasing demands for
higher output power in UMTS handsets. The PA module
is optimized for V
REF
= +2.85 V, a requirement for
compatibility with the Qualcomm廬 6275 chipset. The
device is manufactured on an advanced InGaP HBT
MMIC technology offering state-of-the-art reliability,
temperature stability, and ruggedness. Selectable
bias modes that optimize efficiency for different output
power levels, and a shutdown mode with low leakage
current, increase handset talk and standby time. The
self-contained 4 mm x 4 mm x 1.1 mm surface mount
package incorporates matching networks optimized
for output power, efficiency, and linearity in a 50
