| RoHS Compliant Digital Attenuator, 4-Bit, Single Control, 15 dB 0.5 - 4.0 GHz Features * * * * * * * Single Control CMOS Logic for Each Bit Attenuation: 1 dB Steps to 15 dB Low DC Power Consumption: 50 W Lead-Free TSSOP-16 Package 100% Matte Tin Plating over Copper Halogen-Free "Green" Mold Compound RoHS* Compliant and 260C Reflow Compatible MAATSS0019 V2 Functional Schematic 4,5 RF1 RF2 VS GND GND GND GND GND GND Pin 16 Description The M/A-COM MAATSS0019 is a 4 Bit, 1 dB step GaAs MMIC digital attenuator in a lead-free TSSOP16 surface mount plastic package. The MAATSS0019 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 MAATSS0019 is fabricated using a mature 1 micron GaAs MESFET process. The process features full chip passivation for increased performance and reliability. 8 4 2 1 Pin 1 GND GND VC1 VC2 VC3 VC4 GND GND 4. 5. Required external blocking caps shown.
