PRODUCT DESCRIPTION
This power amplifier module supports dual, tri
and quad band applications for GMSK and 8-PSK
modulation schemes using a polar architecture.
There are two amplifier chains, one to support
GSM850/900 bands, the other for DCS/PCS bands.
Each amplification chain is optimized for excellent
EDGE efficiency, power, and linearity in a Polar loop
environment while maintaining high efficiency in the
GSM/GPRS mode.
The module includes an internal reference voltage
and integrated power control scheme for use in both
GMSK and 8-PSK operation. This facilitates fast and
easy production calibration and reduces the number
of external components required to complete a power
control function.
The amplifier’s power control range is typically
55 dB, with the output power set by applying
an analog voltage to VRAMP. All of the RF ports
for this device are internally matched to 50 .
