PRODUCT DESCRIPTION
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.
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鈥檚 power con-
trol range is typically 55 dB, with the output power set
by applying an analog voltage to V
RAMP
.
All of the RF ports for this device are internally
matched to 50

. Internal DC blocks are provided at
the RF inputs.
