AT-259 General Description
M/A-COM's AT-259 is a GaAs MMIC voltage variable absorptive attenuator in a low cost SOT/143 4-Lead surface mount plastic package. The AT-259 is ideally suited for use where attenuation fine tuning, fast switching and very low power consumption are re q u i red. Typical applications include radio, cellular, GPS equipment and other Automatic Gain/Level Control circuits.
The AT-259 is fabricated with a monolithic GaAs MMIC using a mature 1 micron process. The process features full chip passivation for increased performance and reliability.
