Description

M/A-COM's AT65-0107 is a GaAs FET 6-bit digital
attenuator with a 0.5 dB minimum step size and a 31.5 dB
total attenuation range. This device is in a SOIC-24 wide
body, plastic surface mount package. The AT65-0107 is
ideally suited for use where accuracy, fast speed, very low
power consumption and low costs are required.
