Description

  M/A-COM's AT-109 is a GaAs MMIC voltage variable absorptive attenuator in a low-cost SOIC 8-lead surface mount plastic package. The AT-109 is more linear than the higher attenuation range AT-108. The AT-109 is ideally
suited for use where linear attenuation fine tuning and very low power comsumption are re quired. Typical applications include radio, cellular, GPS equipment and automatic gain/level control circ u i t s .

    The AT-109 is fabricated with a monolithic GaAs MMIC using a mature 1-micron process. The process features full chip passivation for increased perf o rmance and reliability .
