The RF3110 is a high-power, high-efficiency power ampli-
fier module with integrated power control. The device is
self-contained with 50
input and output terminals. The
power control function is also incorporated, eliminating
the need for directional couplers, detector diodes, power
control ASICs and other power control circuitry; this
allows the module to be driven directly from the DAC out-
put. The device is designed for use as the final RF ampli-
fier in GSM/DCS and PCS handheld digital cellular
equipment and other applications in the 880MHz to
915MHz, 1710MHz to 1785MHz and 1850MHz to
1910MHz bands. On-board power control provides over
35dB of control range with an analog voltage input; and,
power down with a logic "low" for standby operation.

Function
Description
Interface Schematic
1
DCS/PCS IN
RF input to the DCS band. This is a 50
input.
2
BAND
SELECT
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.
3
TX ENABLE
This signal enables the PA module for operation with a logic high. Once
TX Enable is asserted the RF output level will increase to 0dBm.
4
VBATT
Power supply for the module. This should be connected to the battery.
5
VREG
Regulated voltage input for power control function. (2.8V nom)
6
VRAMP
Ramping signal from DAC. A simple RC filter may need to be con-
nected between the DAC output and the VRAMP input depending on
the baseband selected. The ramping profiles shown later in the data
sheet are recommended profiles for meeting the GSM specification for
burst timing and transient spectrum.
7
GSM IN
RF input to the GSM band. This is a 50
input.
8
VCC2
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.
9
GSM OUT
RF output for the GSM band. This is a 50
output. The output load line
matching is contained internal to the package.
10
VCC OUT
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).
11
DCS/PCS
OUT
RF output for the DCS band. This is a 50
output. The output load line
matching is contained internal to the package.
12
VCC2
Controlled voltage input to DCS driver stage. This voltage is part of the
power control function for the module. This node must be connected to
