The MAAM-011156 is a GaAs single stage
differential amplifier assembled in a lead-free 3 mm
16-lead PQFN plastic package. This amplifier
provides 19 dB of gain while biased at 8 volts and
also offers a power down function. The amplifier
provides excellent linearity and high output power
with greater than 30 dB MER for 64 QAM
modulation with 16 channels and 58 dBmV per
channel.

4. Exceeding any one or combination of these limits may cause
permanent damage to this device.
5. MACOM does not recommend sustained operation near these
survivability limits.
6. Operating at nominal conditions with TJ ≤ 150°C will ensure
MTTF > 1 x 106 hours.
7. Junction Temperature (TJ) = TC + Өjc * (V * I)
Typical thermal resistance (Өjc) = 16° CW.
a) For TC = +25°C,
TJ = 52°C @ 8 V, 210 mA
b) For TC = +85°C,
TJ = 112°C @ 8 V, 210 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
HBM Class 1B devices.
