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 50ꢀ .

This power amplifier module supports dual, tri and
quad band applications for GMSK and 8-PSK modu-
lation schemes using a polar architecture. There are
two amplifier chains, one to support GSM850/900
bands, the other for DCS/PCS bands. Each amplifica-
tion 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.
