Description
M/A-COM’s AT-267 is a 1 bit, 15 dB step GaAs MMIC
digital
attenuator in a low cost SOT-25 5 lead surface
mount plastic package. The AT-267 is ideally suited for
use where high accuracy, very low power consumption and
low intermodulation products are required.
Typical
applications
include
wireless
handsets,
base
stations, wireless LAN equipment, GPS receivers and any
RF applications with automatic gain/level control circuits.
The AT-267 is fabricated as a monolithic GaAs integrated
circuit using a proven self-aligned gate process.
The
process features full chip passivation for performance and
reliability.
