ALM-1322
1.8-2.2GHz Very Low Noise High Gain Balanced Amplifier Module
Data Sheet
Description
Avago Technologies’ ALM-1322 is a very low noise, high
gain balanced amplifier module operating in the 1.8 to
2.2GHz frequency range. The exceptional noise perfor-
mance is achieved through the use of Avago Technolo-
gies’ proprietary 0.5um GaAs Enhancement-mode pHEMT
process.
The ALM-1322 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), Radiocards and Multi-
Carrier Driver Amplifiers in the cellular/PCS/CDMA bands.

• 5V supply
• Excellent uniformity in product specifications
• Tape-and-Reel packaging option available
• MSL-2a and Lead-free
• Point MTTF > 300 years at 120°C channel temperature
• Specifications
– 2GHz; 5V, 100mA (typ) per section
– Vctrl typically at 2.2V
– 29.9 dB Gain
– 0.57 dB Noise Figure
– 35.6 dBm Output IP3
– 17 dBm Output Power at 1dB gain compression

Applications
• Diversity Antenna, TMA & Front End LNA for EGSM/
PCS/W-CDMA Base Stations.
• Driver amplifier.
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.
ESD Machine Model = 50 V
