| Voltage Variable Absorptive Attenuator, 30 dB 0.5 - 2 GHz AT-110 V 2.00 Features q q q q q q q q SO-8 Single Positive Voltage Control 0 to +5 Volts 30 dB Voltage Variable Attenuation 2 dB Linearity from BSL Low DC Power Consumption Temperature Range: -40C to +85C Low-Cost SOIC 8 Plastic Package Tape and Reel Packaging Available Fast Switching Speed Description M/A-COM's AT-110 is a linear GaAs MMIC voltage variable absorptive attenuator in a low-cost SOIC 8-lead surface mount plastic package. The AT-110 has a faster switching speed than the AT-108 or AT-109. The AT-110 is ideally suited for use where linear attenuation fine tuning and very low power comsumption are required. Typical applications include radio, cellular, GPS equipment and automatic gain/level control circuits. The AT-110 is fabricated with a monolithic GaAs MMIC using a mature 1-micron process. The process features full chip passivation for increased performance and reliability.
