S2
The MAAM-009450 is ideally suited for multi-tuner
set top boxes, home gateways, and other broadband
internet based applications.
Vc
The MAAM-009450 is fabricated using MACOM’s
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.

5. Exceeding any one or combination of these limits may cause
permanent damage to this device.
6. M/A-COM does not recommend sustained operation near
these survivability limits.
7. These operating conditions will ensure MTTF > 1 x 106 hours.
8. Junction Temperature (TJ) = TA + Өjc * (V * I)
Typical thermal resistance (Өjc) = 73 °C/W.
a) For TA = 25°C,
TJ = 72 °C @ 5.0 V, 130 mA
b) For TA = 85°C,
TJ = 129 °C @ 5.0 V, 120 mA
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
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.
