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  
1. Use the C1 control for a single 16-dB bit.  
required.  
Typical applications include dynamic  
range setting in precision receiver circuits and other  
gain/leveling control circuits. Available with en-  
hanced performance as fully hermetic version. Envi-  
ronmentally screenable as P/N AT-273-PIN.
