| RoHS Compliant Digital Attenuator, 30 dB, 4-Bit DC - 2.0 GHz Features * * * * * * * * * * Attenuation 2-dB Steps to 30 dB High Accuracy Low Intermodulation Product: +50 dBm IP3 Low DC Power Consumption: 50 W Temperature Stability +/-0.15 dB: -40C to +85C Lead-Free SOIC-16 Plastic Package 100% Matte Tin Plating over Copper Halogen-Free "Green" Mold Compound 260C Reflow Compatible RoHS* Compliant Version of AT-220 MAADSS0009 V1 Functional Schematic RF1 16 GND 15 GND 14 GND 13 GND GND 12 11 GND 10 RF2 9 16 dB 8 dB 4 dB 2 dB Description M/A-COM's MAADSS0009 is a 4-bit, 2-dB step GaAs MMIC digital attenuator in a lead-free SOIC 16-lead surface mount plastic package. The MAADSS0009 is ideally suited for use where high accuracy, fast switching, very low power consumption and low intermodulation products are required. Typical applications include radio and cellular equipment, wireless LANs, GPS equipment and other Gain/Level Control circuits. The MAADSS0009 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 8 VC1 VC1 VC2 VC2 VC3 VC3 VC4 VC4 Pin Configuration Pin No. 1 2 3 4 5 Function VC1 VC1 VC2 VC2 VC3 VC3 VC4 VC4 Pin No. 9 10 11 12 13 14 15 16 Function RF2 GND GND GND GND GND GND RF1 Ordering Information1 Part Number MAADSS0009 MAADSS0009TR-3000 6 7 Package Lead-Free SOIC 16-Lead 3000 piece reel 8 Absolute Maximum Ratings 2,3 Parameter Input Power 50 MHz 500-2000 MHz Control Voltage Operating Temperature Storage Temperature 1.
