ALM-32320
3.3GHz – 3.9GHz
2 Watt High Linearity Amplifier
Data Sheet
Description
Avago Technologies’ ALM-32320 is a high linearity 2 Watt
PA with good OIP3 performance and exceptionally good
PAE at 1dB gain compression point, achieved through the
use of Avago Technologies’ proprietary 0.25um GaAs En-
hancement-mode pHEMT process.
All matching components are fully integrated within
the module and the 50Ω RF input and output pins are
already internally AC-coupled. This makes the ALM-32320
extremely easy to use as the only external parts are DC
supply bypass capacitors.
The adjustable temperature-compensated internal bias
circuit allows the device to be operated at either class A
or class AB operation. The ALM-32320 is housed inside a
miniature 7.0 x 10.0 x 1.1 mm3 20-lead multiple-chips-on-
board (MCOB) module package.

Note:
1. Enhancement mode technology employs positive gate voltage,
thereby eliminating the need of negative gate voltage associated
with conventional depletion mode devices.
