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.

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

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.
