Description  
1. Use the C1 control for a single 16-dB bit.  
M/A-COM's AT-273-PIN is a GaAs FET digital  
attenuator with a 16.0 dB minimum step size and a  
32 dB total attenuation range. This attenuator and  
integral TTL driver is in a hermetically sealed  
ceramic 16-lead surface mount package. The AT-  
273-PIN is ideally suited for use where accuracy,  
fast switching, very low power consumption and low
