PRODUCT DESCRIPTION
This power amplifier module supports dual, tri and
quad band applications for GMSK and 8-PSK modu-
lation schemes using an open loop polar architec-
ture. 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 num-
ber 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 50Ω.
