ALM-31222
1.7-2.7GHz
1-Watt High Linearity Amplifier
Data Sheet
Description
Avago Technologiesâ ALM-31222 is a high linearity 1 Watt
PA with good OIP3 performance and exceptionally good
PAE at 1dB gain compression point, achieved through the
use of Avago Technologiesâ proprietary 0.25um GaAs En-
hancement-mode pHEMT process.
All matching components are fully integrated within the
module. This makes the ALM-31222 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-31222 is housed inside a miniature 5.0 x 6.0 x 1.1
mm3 22-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.
Attention: Observe precautions for
handling electrostatic sensitive devices.
ESD Machine Model = 200 V
ESD Human Body Model = 700 V
