Description
The MAADSS0016 is a 5-Bit, 1dB step GaAs MMIC
digital attenuator in a lead-free 3mm 16 lead PQFN
surface mount plastic package. This device 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.
3. Blocking capacitors are required on all RF ports.
4. RF Port and Ground pin capacitors are 1000 pF.

The MAADSS0016 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.
5. The exposed pad centered on the package bottom should
be grounded.

Handling Procedures
Please observe the following precautions to avoid
damage:
Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive
to electrostatic discharge (ESD) and can be
damaged by static electricity. Proper ESD control
techniques should be used when handling these
devices.
