V2 Functional Schematic3,4 Description The MAADSS0014 is a 4-Bit, 2dB step GaAs MMIC digital attenuator in a lead-free 3mm PQFN-16LD surface mount plastic package. The MAADSS0014 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 MAADSS0014 is part of a digital attenuator family. This family includes 4, 5, and 6 bit attenuators with 0.5, 1, or 2 dB steps and up to 31.5 range. 3. Blocking capacitors are required on all RF ports. 4. RF Port and Ground pin capacitors are 1000 pF. Pin Configuration5 Pin No. 1 2 3 4 5 6 7 Function VDD RF In/Out Ext. C to GND Ext. C to GND Ext. C to GND Ext. C to GND Ext. C to GND Ext.
