Function
DCS/PCS IN
BAND
SELECT
TX ENABLE
Description
RF input to the DCS band. This is a 50
input.
Allows external control to select the GSM or DCS band with a logic high
or low. A logic low enables the GSM band whereas a logic high enables
the DCS band.
This signal enables the PA module for operation with a logic high. Once
TX Enable is asserted the RF output level will increase to -2dBm.
Power supply for the module. This should be connected to the battery.

VRAMP
Regulated voltage input for power control function. (2.8V nom)
nected between the DAC output and the VRAMP input depending on
the baseband selected.
RF input to the GSM band. This is a 50
input.
Controlled voltage input to driver stage for GSM bands. This voltage is
part of the power control function for the module. This node must be
connected to V
CC
out.
RF output for the GSM band. This is a 50
output. The output load line
matching is contained internal to the package.
Controlled voltage output to feed V
CC2
. This voltage is part of the
power control function for the module. It can not be connected to any-
thing other than V
CC2
, nor can any component be placed on this node
(i.e., decoupling capacitor).
