RoHS Compliant 3 Volt Voltage Variable Attenuator 25 dB, DC-2.5 GHz Features • • • • • • • • MAAVSS0006 V1 Functional Schematic 1 Single Voltage Control: 0 to -3 Volts 25 dB Attenuation Range at 0.9 GHz Low DC Power Consumption Lead-Free SOT-25 Package 100% Matte Tin Plating over Copper Halogen-Free “Green” Mold Compound 260°C Reflow Compatible RoHS* Compliant Version of AT-255 Vc GND 5 4 Description M/A-COM’s MAAVSS0006 is a GaAs MMIC voltage variable absorptive attenuator in a lead-free SOT-25 surface mount plastic package. The MAAVSS0005 is ideally suited for use where variable attenuation, fine tuning, and very low power consumption are required. Typical applications include radio, cellular, GPS equipment and automatic gain/level control circuits. The MAAVSS0006 is fabricated using a mature 1-micron GaAs MESFET process. The process features full chip passivation for increased performance and reliability. Ordering Information 1 2 3 RF GND RF 1. VC = -3 V to 0 V @ 25 µA maximum.
