Description
M/A-COM’s AT-210 is a 4-bit, 1-dB step GaAs MMIC
digital 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.
