The ACPM-7881 is a high performance W-CDMA power
amplifer module ofered in a 4x4x1.1mm package. De-
signed around Avago Technologies’ GaAs Enhancement
Mode pHEMT process, the ACPM-7881 ofers premium
power added efciency and linearity in a very small form
factor. The PA is fully matched to 50 Ohms on the input
and output.
The amplifer has excellent ACLR and efciency 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.
