Description  
M/A-COM’s AT-250 is a GaAs MMIC voltage variable absorptive  
attenuator in a low cost SOIC 8-lead surface mount plastic pack-  
age. The AT-250 is ideally suited for use where attenuation fine  
tuning, fast switching and very low power consumption are  
required. Typical applications include radio, cellular, GPS equip-  
ment and other Automatic Gain/Level Control circuits.  
Ordering Information  
Part Number  
The AT-250 is fabricated with a monolithic GaAs MMIC using a  
mature 1-micron process. The process features full chip passiva-  
tion for increased performance and reliability.
