Description
M/A-COM’s AT-250 is a GaAs MMIC voltage variable absorptive attenuator in a low cost SOIC 8- lead surface mount plastic package. The AT-250 is ideally suited for use where attenuation fine tuning, fast switching and very low power consumption are required.
Typical applications include radio, cellular, GPS equipment and other automatic gain/level control circuits.
The AT-250 is fabricated with a monolithic GaAs MMIC using a mature 1-micron process. The process features full chip passivation for increased performance and reliability.
