Digital Attenuator, 15.5 dB, 5-Bit,

TTL Driver, DC-3.5 GHz

Features

Description

M/A-COM's AT90-0283 is a GaAs FET 5-bit digital

attenuator with integral TTL driver. Step size is 0.5 dB

providing a 15.5 dB total attenuation range. This device is

in an FQFP-N plastic surface mount package. The AT90-

0283 is ideally suited for use where accuracy, fast speed,

very low power consumption and low costs are required.
