AWT6201
GSM850/GSM900/DCS/PCS
Quad Band PowerPlexer
TM
with Integrated Power Control
Advanced Product Information - Rev 0.7
The module requires only the most basic RF
decoupling, all the RF ports are 50鈩? and interfaces
directly with the baseband power control DAC. The
solution includes integrated power control, two dual
band power amplifiers to support GSM850/900/DCS/
PCS, harmonic filtering and RX/TX switching.
The power amplifiers support class 12 GPRS, 4 TX
slots at 50% duty cycle, using three stage InGaP HBT
PAs. The pHEMT switches support 4 RX ports to in-
terface with external RX SAW filters and the filtering
is achieved using integrated passives technology.
The integrated power control scheme reduces the
number of external components associated with a
power control function, and facilitates fast and easy
production calibration. The power control range is
typically 55dB.
