Description
The MAAM-011194 is an integrated 3 stage
differential amplifier with embedded voltage variable
attenuator. This part is intended as the output
amplifier in a downstream Edge QAM RF modulator
to support DOCSIS3.1 applications. The module
provides high gain, low noise figure and excellent
linearity and ACPR at output levels 7 dB above
Cable Labs DRFI requirements. The voltage variable
attenuator (VVA) is implemented with PIN diodes to
provide continuous power level control with high
linearity with a single control voltage. The part is
packaged in a 5 x 7 mm PQFN package.

Maximum Operating Condition8
Parameter Maximum Operating
Condition
RF Input Power9 -6 dBm
Voltage 6 volts
Operating Temperature -40°C to +100°C
Junction Temperature10 +155°C
8. Operating at nominal conditions with TJ < 155°C will ensure
MTTF > 1 x 106 hours.
9. Assumes maximum gain state. For each dB of attenuation the
maximum RF Input Power may increase by 1 dB up to
+7 dBm.
10. Junction Temperature (TJ) = TC + ӨJC * (V * I)
Typical thermal resistance (ӨJC) = 14.6°C/W.
a) For TC = 25°C,
TJ = 71 °C @ 6 V, 520 mA (Stage3, ID3 )
b) For TC = 100°C,
TJ = 141 °C @ 6 V, 470 mA (Stage3, ID3 )
Handling Procedures
Please observe the following precautions to avoid
damage:
Static Sensitivity
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.
Printed Circuit Board (PCB)
Thermal Design
To maintain reliable junction temperatures for this
high power amplifier the printed circuit board must
provide low thermal resistance to the exposed
paddle of the IC package. This requires both a large
array of high thermal conductive vias beneath the IC
as well as good heat sinking at the back of side of
the PCB. In general, thinner substrates and thicker
plating for vias provide lower thermal resistance.
For a standard 62 mil board the following copper
plating thickness for vias and top and bottom metal
layers are recommended.
Vias plated to 2-mil (50 µm) thickness of copper.
Finished via diameter 9.5 mils (0.25 mm).
Via spacing 20 mils (0.51 mm).
2.8-mil (70 µm) thick copper for top and bottom
metal.

Absolute Maximum Ratings11,12,13
Parameter Absolute Maximum
RF Input Power11 -3 dBm
Voltage 9 volts
Storage Temperature -65°C to +150°C
11. Assumes maximum gain state, for each dB of attenuation the
maximum RF input power may increase by 1 dB up to +10 dBm.
12. Exceeding any one or combination of these limits may cause
permanent damage to this device.
13. MACOM does not recommend sustained operation near these
survivability limits.
