Description
M/A-COM’s AT-220 is a 4-bit, 2-dB step GaAs MMIC
digital attenuator in a low cost SOIC 16-lead surface
mount plastic package. The AT-220 is ideally suited for
use where high accuracy, fast switching, very low power
consumption and low intermodulation products are
required. Typical applications include radio and cellular
equipment, wireless LANs, GPS equipment and other
Gain/Level Control circuits.
The AT-220 is fabricated with a monolithic GaAs MMIC
using a mature 1-micron process. The process features
full chip passivation for increased performance and
reliability.
