Description
M/A-COM's AT65-0263 is a GaAs FET 5-bit digital
attenuator with integral TTL driver. Step size is 1.0
dB providing 31 dB total attenuation range. This
device is in a SOW -16 plastic surface mount
package. The AT65-0263 is ideally suited for use
where accuracy, fast speed, very low power
consumption and low costs are required
