P_ThR_isO_pD_oU_wC_erT_aD_mE_pS_lifiC_erR_mIP_oT_dI_uO_leN_{   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 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 volt-
age to VRAMP. All of the RF ports for this device are DC
blocked and internally matched to 50 .
