Description  
M/A-COM's AT-260 is a 5-bit, 1-dB step GaAs MMIC digi-  
tal attenuator in a low cost SSOP-20 surface mount plastic  
package. The AT-260 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-260 is fabricated with a monolithic GaAs MMIC  
using a mature 1-micron process. The process features full  
chip passivation for increased performance and reliability.
