| RoHS Compliant Digital Attenuator, 15.5 dB, 5-Bit DC - 2.0 GHz Features * * * * * * * * * * 0.5 dB Attenuation Steps to 15.5 dB Ultra Low DC Power Consumption Low Intermodulation Product: +45 dBm IP3 Tape and Reel Packaging Available Temperature Stability: +/-0.15 dB from -40C to +85C Lead-Free SOIC-16 Package 100% Matte Tin Plating over Copper Halogen-Free "Green" Mold Compound 260C Reflow Compatible RoHS* Compliant Version of AT-280 MAATSS0021 V1 Functional Schematic 16 15 14 13 12 11 10 9 8 dB 4 dB 2 dB 1 dB 0.5 dB Description M/A-COM's MAATSS0021 is a 5-bit, 0.5-dB step GaAs MMIC digital attenuator in a lead-free SOIC-16 surface mount plastic package. The MAATSS0021 is ideally suited for use where high accuracy, fast switching, very low power consumption and low intermodulation products are required at a low cost. Typical applications include radio and cellular equipment, wireless LANS, GPS equipment and other gain/level control circuits. The MAATSS0021 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 Pin Configuration Pin No. 1 2 3 4 5 6 7 Function VC1 VC1 VC2 VC2 VC3 VC3 VC4 VC5 Pin No. 9 10 11 12 13 14 15 16 Function RF2 Ground Ground Ground Ground Ground Ground RF1 Ordering Information Part Number MAATSS0021 MAATSS0021TR-3000 MAATSS0021SMB 8 Absolute Maximum Ratings 1,2 Package Bulk Packaging 3000 piece reel Sample Board Parameter Input Power: 0.05 GHz 0.5 - 2.0 GHz Control Voltage Operating Temperature Storage Temperature Absolute Maximum +27 dBm +34 dBm -8.5 V < VC < +5 V -40C to +85C -65C to +150C Note: Reference Application Note M513 for reel size information. 1.
