Description
The MAAM-009879 CATV 2-way active splitter with
the default loop-thru path is a GaAs MMIC which
exhibits low noise figure and distortion in a lead-free
3mm 12-lead PQFN plastic package. The design
features 75
Ω
inputs and outputs.
The MAAM-009879 is ideally suited for multi-tuner
set top boxes, home gateways, and other broadband
internet based applications.
The MAAM-009879 is fabricated using M/A-COM
Technology’s E/D pHEMT process to realize default
loop-thru 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:
5. Exceeding any one or combination of these limits may cause
permanent damage to this device.
6. M/A-COM Technology does not recommend sustained
operation near these survivability limits.
7. These operating conditions will ensure MTTF > 1 x 10
6
hours.

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