Description  
M/A-COM's AT-280 is a 5-bit, 0.5 dB-step GaAs MMIC  
digital attenuator in a low cost SOIC 16-lead surface mount  
plastic package. The AT-280 is ideally suited for use where  
high accuracy, fast switching, very low power consumption  
and low intermodulation products are required at a low  
cost. Typical applications include radio and cellular  
equipment, wireless LANS, GPS equipment and other  
Gain/Level Control circuits.  
Ordering Information  
The AT-280 is fabricated with a monolithic GaAs MMIC  
using a mature 1-micron process. The process features full  
chip passivation for increased performance and reliability.
