Description  
M/A-COM’s AT20-0273 is  
a
GaAs FET digital  
attenuator with a 16 dB minimum step size and 32 dB total  
attenuation. This attenuator and integral TTL driver is in a  
sealed ceramic 16-lead surface mount package. The  
AT20-0273 is ideally suited for use where accuracy, fast  
switching, very low power consumption and low  
intermodulation products are required. Typical applications  
include dynamic range setting in precision receiver circuits  
and other gain/leveling control circuits. Available with  
enhanced performance as fully hermetic version.  
Environmentally screenable as P/N AT-273.
