AT-635

Voltage Variable Absorptive Attenuator, 35 dB DC - 2 GHz AT-635 V 3.00 Features q q q q q q q SO-14 35 dB Voltage Variable Attenuation @ 1 GHz Single Voltage Control 0 to -4 Volts Low DC Power Consumption: 10 mW Nanosecond Switching Speed Temperature Range: -40˚C to +85˚C Low Cost SOIC14 Plastic Package Tape and Reel Packaging Available1 Description M/A-COM’s AT-635 is a GaAs MMIC voltage variable absorptive attenuator in a low cost SOIC 14-lead surface mount plastic package. The AT-635 is ideally suited for use where attenuation fine tuning, fast switching and very low power consumption are required. Typical applications include radio, cellular, GPS equipment and other Automatic Gain/Level Control circuits. The AT-635 is fabricated with a monolithic GaAs MMIC using a mature 1-micron process. The process features full chip passivation for increased performance and reliability.
