MAATSS0018 Digital Attenuator, 10 dB, 1-Bit DC - 2.0 GHz Functional Block Diagram Features Rev. V3 Single 10 dB Step Low Loss: 0.3 dB @ 900 MHz Lead-Free SOT-25 Package 100% Matte Tin Plating over Copper Halogen-Free "Green" Mold Compound 260C Reflow Compatible RoHS* Compliant Version of AT-266 RF1 GND Description The MAATSS0018 is a 1 bit, 10 dB step GaAs MMIC digital attenuator in a lead-free SOT-25 surface mount plastic package. This device uses a mature 1-micron process. The process features full chip passivation for increased performance and reliability. The MAATSS0018 is ideally suited for use where high accuracy, very low power consumption and low intermodulation products are required. Typical applications include radio, wireless LANs, GPS equipment and other gain / level control circuits.

For positive voltage control, external DC blocking capacitors are required on all RF ports (pins 1, 2 and 3) 6. Differential voltage, V(state 1) - V(state 0), must be +2.8 V minimum and less than 8 V. 7. 0 = -8 V to 0.2 V, 1 = -0.2 V to 8 V 3. Exceeding any one or combination of these limits may cause permanent damage to this device. 4. MACOM does not recommend sustained operation near these survivability limits. 2 MACOM Technology Solutions Inc.
