ALM-31222-TR2G

P1-P3P4-P6P7-P9P10-P12P13-P13
ALM-31222
1.7-2.7GHz
1-Watt High Linearity Amplier
Data Sheet
Description
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.
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
mm
3
22-lead multiple-chips-on-board (MCOB) module
package.

Specications
2GHz; 5V, 415mA (typical)
• 14.9 dB Gain
• 47.9 dBm Output IP3
• 31.5 dBm Output Power at 1dB gain compression
• 52.6% PAE at P1dB
• 2.7 dB Noise Figure
Applications
• Class A driver amplier for GSM/PCS/W-CDMA/WiMAX
Base Stations.
• General purpose gain block.
Note:
1. Enhancement mode technology employs positive gate voltage,
thereby eliminating the need of negative gate voltage associated
with conventional depletion mode devices.
