MAAM-008863
FTTx RF Amplifier
50 - 1000 MHz
Rev. V5
The MAAM-008863 is fabricated using MACOM’s
low noise GaAs pHEMT technology in a lead-free 4
mm 24-lead package. The amplifier requires a
minimal number of off-chip components resulting in
a highly integrated low cost solution.

Description
The MAAM-008863 provides high gain, low noise
and low distortion amplification of the downstream
CATV signal in fiber-to-the-home (FTTH)
applications. This device is ideally suited for
interfacing with the RF video output of optical
triplexers used within optical network terminals
(ONTs).

6. Exceeding any one or combination of these limits may cause
permanent damage to this device.
7. MACOM does not recommend sustained operation near these
survivability limits.
8. Operating at nominal conditions with TJ ≤ +150°C will ensure
MTTF > 1 x 106 hours.
9. Junction Temperature (TJ) = TC + Өjc * ((V * I) - (POUT - PIN))
Typical thermal resistance (Өjc) = 19°C/W.
a) For TC = 25°C,
TJ = 46 °C @ 5 V, 220 mA
b) For TC = 85°C,
TJ = 106 °C @ 5 V, 220 mA
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.
