The AT-108 is ideally suited for use where linear attenuation fine tuning and very low power consumption are required. Typical applications include radio, cellular, GPS equipment and automatic gain/level control circuits. The AT-108 is fabricated with a monolithic GaAs MMIC using a mature 1-micron process. The process features full chip passivation for increased performance and reliability. .0532/.0688 (1.35/1.75) .004 (0.10) BSC. .050 (1.27) .0040/.0098 (.10/.25) -C- CHAMFER (OPTIONAL ) 0°/80° .013/.020 (8 (.33/.51) PL) M C AM B S .010(.25) .016/.050 (0.40/1.27) .0075/.0098 (.19/.25) 1.
