ALM-1222
1.8-2.2GHz Low Noise, High Gain, High Linearity Bal-
anced Amplifier Module
Data Sheet
Description
Avago Technologies’ ALM-1222 is a very low noise, high
linearity balanced amplifier module operating in the 1.8
to 2.2GHz frequency range. The exceptional noise and
linearity performances are achieved through the use of
Avago Technologies’ proprietary 0.5um GaAs Enhance-
ment-mode pHEMT process.
The ALM-1222 is housed in a miniature 5.0 x 6.0 x 1.1
mm3 22-lead multiple-chips-on-board (MCOB) module
package. The compact footprint and low profile makes
this product an ideal choice for Wireless Infrastructure
Basestation Tower-Mounted Amplifiers (TMA), Radio-
cards and Multi-Carrier Driver Amplifiers in the cellular/
PCS/CDMA bands.

Notes:
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.
