Description
M/A-COM’s AT-210 is a 4-bit, 1-dB step GaAs MMIC digi-
tal attenuator in a low cost SOIC 16-lead surface mount
plastic package. The AT-210 is ideally suited for use where
high accuracy, fast switching, very low power consumption
and low intermodulation products are required. Typical
applications include radio, cellular, and wireless LANs, GPS
equipment and other Gain/Level Control circuits.
The AT-210 is fabricated with a monolithic GaAs MMIC
using a mature 1-micron process. The process features full
chip passivation for increased performance and reliability.
