Description  
M/A-COM’s AT-263 is  
a GaAs FET 5-bit digital  
attenuator with a 1 dB minimum step size and 31 dB total  
attenuation. This attenuator and integral TTL driver is in a  
hermetically sealed ceramic 16-lead surface mount package.  
The AT-263 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. Environmental  
screening is available. Contact the factory for information.
