MAAV-008022 3 Volt Voltage Variable Absorptive Attenuator 40 dB, 0.5 - 2.0 GHz Functional Schematic 2,3,4,5 Features Rev. V1 Single Positive Voltage Control: 0 to +3 Volts 40 dB Attenuation Range at 0.9 GHz 2 dB Linearity from BSL Low DC Power Consumption 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-113 8 7 6 5 1 2 3 4 Description M/A-COM's MAAV-008022 is a GaAs MMIC voltage variable absorptive attenuator in a lead-free low-cost SOIC 8-lead surface mount plastic package. The MAAV-008022 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 MAAV-008022 is fabricated with a monolithic GaAs MMIC using a mature 1-micron process. The process features full chip passivation for increased performance and reliability.
