Description
M/A-COM's AT90-1107 is a GaAs FET 6-bit digital
attenuator with integral TTL driver. Step size is 0.5 dB pro-
viding a 31.5 dB total attenuation range. This device is in an
FQFP-N plastic surface mount package. The AT90-1107 is
ideally suited for use where accuracy, fast speed, very low
power consumption and low costs are required.
