Description
M/A-COM's MAAD-009170-000100 is a GaAs
pHEMT 5-bit digital attenuator with integral TTL
driver in an PQFN plastic surface mount package.
Step size is 0.5 dB providing a 15.5 dB total
attenuation range. This design has been optimized
to minimize phase variation over the attenuation
range. MAAD-009170-000100 is ideally suited for
use where accuracy, fast switching, very low power
consumption and low intermodulation products are
required. Typical applications include dynamic range
setting in precision receiver circuits and other gain/
leveling control circuits.

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.
Moisture Sensitivity
The MSL rating for this part is defined as Level 2
per IPC/JEDEC J-STD-020. Parts shall be stored
and/or baked as required for MSL Level 2 parts.
