The amplifier is ideally suited for use in CATV return
path applications, including DOCSIS 3.1 systems: it
offers low distortion and low noise figure with high
gain. It typically provides 3.1 dB noise figure,
21.2 dB gain, and 30 dB MER up to 57 dBmV per
channel for 16-Channel 64 QAM signaling while
drawing 290 mA DC current @ 5 V bias.

5. Modulation Error Ratio, 64 QAM 5.12 MS/s. See ‘Typical Performance Curves’ on page 5 of this datasheet for an example MER vs.
output power relationship.
6. Data corresponds to the typical application circuit and component values shown on page 3 of this datasheet. Parameters shown at
nominal ICC = 290 mA unless otherwise noted. ICC is the total DC current draw from the VCC supply. As shown on page 3, it is distributed to
pins 9 and 12 by balun T2 and pins 10 and 11 directly. Resistor R2 determines the DC voltage of ABIASA/B and thereby ICC at approximately
0.25 mA/Ω. See page 5 for a typical ICC vs. R2 relationship assuming VCC = 5 V.

Storage Temperature
+150°C
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.
-40°C to +85°C
-65°C to +125°C
7. Exceeding any one or a combination of these limits may cause
permanent damage to this device.
8. MACOM does not recommend sustained operation near these
survivability limits.
9. Operating at nominal conditions with TJ ≤ 150°C will ensure
MTTF > 1 x 106 hours.
10.Junction Temperature (TJ) = TC + Өjc * (V * I)
Typical thermal resistance (Өjc) = 15° C/W.
a) For TC = +25°C, TJ = 47°C @ 5 V, 290 mA
b) For TC = +85°C, TJ = 107°C @ 5 V, 290 mA
