V1 Functional Schematic 2,3,4 8 7 6 5 Description M/A-COM’s AT-110-2 is a GaAs MMIC voltage variable absorptive attenuator in a low-cost SOIC 8lead surface mount plastic package. The AT-110-2 has a faster switching speed than the AT-108 or AT-109. The AT-110-2 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-110-2 is fabricated with a monolithic GaAs MMIC using a mature 1-micron process. The process features full chip passivation for increased performance and reliability. 1 2 3 4 2. VCC = +5 VDC ± 0.5 VDC @ 300 µA maximum. 3. VC = 0 VDC to +5 VDC @ 6 mA maximum. 4.
