Description
M/A-COM’s MAADSS0012 is a 1-bit, 21 dB step
attenuator. This GaAs MMIC digital attenuator is
packaged in an ultra small lead free 2 mm 8-Lead
PDFN surface mount package.
The MAADSS0012 digital attenuator will work with
any power source operating between 2.8 and 5.0
volts. This single bit attenuator is ideally suited for
use in wide band systems, up to 8.0 GHz where
good linearity and low insertion loss are required.

Handling Procedures
Please observe the following precautions to avoid
damage:
Static Sensitivity
Lead-Free 2 mm 8-Lead PDFN†
†
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.
Reference Application Note S2083 for lead-free solder reflow recommendations.
Meets JEDEC moisture sensitivity level 1 requirements.
Plating is 100% matte tin over copper.

This data shows the MAADSS0012 with the board and connector loss removed.
M/A-COM recommends using DC-Blocking capacitors large enough that their X c is insignificant at the frequency
of use. At 800 MHz a capacitor value greater than 1000 pF is recommended.
