| RoHS Compliant Voltage Variable Absorptive Attenuator 12 dB, DC-2.0 GHz Features * * * * * * * * * * * 12 dB Voltage Variable Attenuation Low Intermodulation Products Low DC Power Consumption: 50 W Single Voltage Control: 0 to -4 Volts Nanosecond Switching Speed Temperature Range: -40C to +85C Lead-Free SOIC-8 Plastic Package 100% Matte Tin Plating over Copper Halogen-Free "Green" Mold Compound 260C Reflow Compatible RoHS* Compliant Version of AT-250 MAAV-007941 V1 Functional Schematic RF2 8 GND 7 GND 6 GND 5 Description M/A-COM's MAAV-007941 is a GaAs MMIC voltage variable absorptive attenuator in a low cost lead-free SOIC 8-lead surface mount plastic package. The MAAV-007941 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 MAAV-007941 is fabricated with a monolithic GaAs MMIC using a mature 1-micron process. The process features full chip passivation for increased performance and reliability.
