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.
