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. This makes the ALM-32320 extremely easy to use.
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.

12.6 dB Gain
51.0 dBm Output IP3

Applications
Class A driver amplifier for WiMAX base stations.
General purpose gain block.
Note:
1. Enhancement mode technology employs positive gate voltage,
thereby eliminating the need of negative gate voltage associated
with conventional depletion mode devices.
2. Good RF practice requires all unused pins to be earthed.
Attention: Observe precautions for
handling electrostatic sensitive devices.

wafer lots. TA = 25°C, Vdd = 5V, Vctrl = 5V, RF performance at 3.5GHz
unless otherwise specified. Future wafers allocated to this product
may have nominal values anywhere between the upper and lower
limits.
6. Measurements are made on a production test board. Input trace
losses have not been de-embedded from actual measurements.
