PRODUCT DESCRIPTION
The AWT6225R power amplifier module supports
GSM/GPRS dual, tri, or quad band operation and
WCDMA operation in the IMT band. In addition, the
AWT6225R module is manufactured using
ANADIGICS’ advanced InGaP HBT MMIC technol-
ogy to provide reliability, temperature stability, and
ruggedness. This penta-band module consists of
three separate amplifier chains; one to support
GSM/GPRS in cellular bands, one to support GSM/
GPRS in DCS/PCS bands, and one to support
WCDMA in the IMT band. The AWT6225R module
includes an internal reference voltage and integrated
power control with temperature compensation for
use in the GSM/GPRS mode. These features facili-
tate fast and easy production calibration, minimize
performance variation over temperature, and reduce
the number of external components required.
The WCDMA PA incorporates ANADIGICS’ HELP2
TM
technology. Through selectable bias modes, the
AWT6225R achieves optimal efficiency across
different output power levels, specifically at low and
mid-range power levels where the PA typically oper-
ates, thereby dramatically increasing handset talk-
time and standby-time. Its built-in voltage regulator
eliminates the need for an external reference
voltage and switch components, reducing PCB area
and BOM costs. All of the RF ports for this device are
internally matched to 50
. The RF inputs GSM_IN
and DCS/PCS_IN both have shunt resistors to
ground to maintain a good input VSWR as the VRAMP
power control voltage is varied. Internal DC blocks
are provided at the RF outputs.
