Description

The ACPM-7881 is a high performance W-CDMA power

amplier module oered in a 4x4x1.1mm package. De-

signed around Avago Technologies’ GaAs Enhancement

Mode pHEMT process, the ACPM-7881 oers premium

power added eciency and linearity in a very small form

factor. The PA is fully matched to 50 Ohms on the input

and output.

The amplier has excellent ACLR and eciency perfor-

mance at max Pout, 28.5dBm, and low quiescent current

(50mA) with a single bias control voltage, Vctrl = 2.0V. No

regulated voltages are required to set the bias, Vdd2 can

be connected directly to the battery.

Designed in a surface mount RF package, the ACPM-7881

is very cost and size competitive.

1 Vdd1 Supply bias 1

and 2

stages drain bias, nominally 3.5V

2 RFin RF input W-CDMA signal input, internally grounded through

inductor. External DC block needed if DC voltage

present on input trace.

3 N/C No internal connection Recommend ground connection on PCB

4 Vctrl Control voltage Output level control, nominally 2V

5 Vdd2 Supply bias Bias circuit supply, > 2.5V; nominally 2.85V.

Does not require a regulated input and can be

connected directly to the battery, if desired.
