| RoHS Compliant Digital Attenuator, 4-Bit, Single Control 30 dB, 0.5 - 2.0 GHz Features * * * * * * * * Positive Single Control 2-dB Attenuation Steps to 30 dB Low DC Power Consumption Lead-Free TSSOP-16 Plastic Package 100% Matte Tin Plating over Copper Halogen-Free "Green" Mold Compound 260C Re-flow Compatible RoHS* Compliant Version of AT-264 MAATSS0016 V2 Functional Schematic 4,5 Vs 16 15 14 13 12 1 11 10 9 Description M/A-COM's MAATSS0016 is a 4-bit, 2-dB step GaAs MMIC digital attenuator in a lead-free TSSOP-16 surface mount plastic package. The MAATSS0016 is ideally suited for use where high accuracy, very low power consumption and low intermodulation products are required. Typical applications include radio, cellular, wireless LANs, GPS equipment and other gain/level control circuits. The MAATSS0016 is fabricated using a mature 1 micron GaAs MESFET process. The process features full chip passivation for increased performance and reliability. 16 8 4 2 1 2 3 4 5 6 7 8 4. 5. Blocking capacitors are required on all RF ports (39 pF used for data measurements). Vs = +5 0.2 VDC must be applied at RF1 or RF2 using a 10 Kohm or greater pull-up resistor.
