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.

Features
Fully matched, input and output
High linearity and P1dB
Unconditionally stable across load condition
Built-in adjustable temperature compensated internal
bias circuitry
GaAs E-pHEMT Technology[1]
5V supply
Excellent uniformity in product specifications
Tape-and-Reel packaging option available
MSL-3 and Lead-free

Specifications
3.5GHz; 5V, 810mA (typical)
12.6 dB Gain
51.0 dBm Output IP3
34.5 dBm Output Power at 1dB Gain Compression
46.6% PAE at P1dB
2.5dB Noise Figure
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.
ESD Machine Model = 80 V
