PRODUCT DESCRIPTION
The AWT6201 is the second generation GSM
PowerPlexer
TM
. It has been developed to minimize
time to market for GSM handset/PDA designers.
The module requires only the most basic RF
decoupling, all the RF ports are 50
,
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.
