ALM-31222
1.7-2.7GHz
1-Watt High Linearity Amplifier
Data Sheet
Features
Description
ꢀ Fully matched, input and output
ꢀ High linearity and P1dB
Avago Technologies’ 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 Technologies’ proprietary 0.25um GaAs En-
hancement-mode pHEMT process.
ꢀ Unconditionally stable across load condition
ꢀ Built-in adjustable temperature-compensated internal
bias circuitry
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.

Notes:
Note:
Package marking provides orientation and identification
“31222” = Device Part Number
1. Enhancement mode technology employs positive gate voltage,
thereby eliminating the need of negative gate voltage associated
with conventional depletion mode devices.
“WWYY”= Work week and Year of manufacture
“XXXX” = Last 4 digit of Lot number
Attention: Observe precautions for
handling electrostatic sensitive devices.
ESD Machine Model = 200 V
ESD Human Body Model = 700 V
