S2
The MAAM-009779 is ideally suited for multi-tuner
set top boxes, home gateways, and other broadband
internet based applications.
Vc
The MAAM-009779 is fabricated using M/A-COM
Technology Solutions’ E/D pHEMT process to
realize default loop-through operation, low noise and
low distortion. The process features full passivation
for robust performance and reliability.

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. An external protection circuit using an
anti-parallel diode pair can be used to protect the
IC.
Please reference application note AN3028 on
http://www.macomtech.com for further detail.
