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.

Unless Otherwise Noted: .xxx = ± 0.010 (.xx = ± 0.25)  
.xx = ± 0.02 (.x = ±0.5)  
Ordering Information  
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.
