Description
M/A-COM’s AM40-0023 is a dual-channel, ultra low noise
amplifier in a surface mount package. Very low noise
figure is achieved by using discrete pHEMT devices com-
bined with M/A-COM’s glass technology. The
AM40-0023 is designed specifically for use in DCS-1800
and PCS telecommunication applications where less than
1 dB noise figure is required.
