| RoHS Compliant Voltage Variable Absorptive Attenuator 35 dB, DC - 2.0 GHz Features * * * * * * * * * * * 35 dB Voltage Variable Attenuation at 1 GHz Single Voltage Control: 0 to -4 Volts Low DC Power Consumption Nanosecond Switching Speed Temperature Range: -40C to +85C Lead-Free SOIC-14 Package 100% Matte Tin Plating over Copper Halogen-Free "Green" Mold Compound 260C Reflow Compatible RoHS* Compliant Version of AT-635 Tape and Reel Packaging Available MAAVSS0004 V1 Functional Schematic 14 13 12 11 10 9 8 Description M/A-COM's MAAVSS0004 is a GaAs MMIC voltage variable absorptive attenuator in a low cost SOIC 14-lead surface mount plastic package. The MAAVSS0004 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 MAAVSS0004 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 5 6 7 Pin Configuration Pin No. 1 2 3 4 5 6 7 Function VC Ground Ground Ground Ground Ground Ground Pin No. 8 9 10 11 12 13 14 Function RF2 Ground Ground Ground Ground Ground RF1 Ordering Information1 Part Number MAAVSS0004 MAAVSS0004TR-3000 Absolute Maximum Ratings 2,3 Package Bulk packaging 3000 piece reel Parameter Input Power Control Voltage Operating Temperature Storing Temperature Absolute Maximum +21 dBm -8.5 V < VC < +5 V -40C to +85C -65C to +150C 1.
