Description

M/A-COM’s AT90-1233 is a GaAs FET 4-Bit digital

attenuator with integral driver. Step size is 2 dB providing

a 30 dB attenuation range. This device is in an FQFP-N

plastic surface mount package. The AT90-1233 is suited

for single supply applications where accuracy, fast speed,

low power consumption and low costs are required.
