Description
M/A-COM’s MAAMSS0044 is a GaAs PHEMT MMIC
amplifier in a lead-free 4 mm 20-lead PQFN
package. The MMIC design is configured as a pair
of cascode PHEMT amplifiers for broadband
performance. It is designed for integration in a 75 Ω
push-pull, low distortion, amplifier circuit. The
device is ideally suited for use in CATV, FTTX, DBS,
and HDTV applications where low noise figure and
low distortion are required.

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) = TC + Өjc * ((V * I) - (POUT - PIN))
Typical thermal resistance (Өjc) = 39° C/W.
a) For TC = 25°C,
TJ = 69 °C @ 5 V, 225 mA
b) For TC = 85°C,
TJ = 129 °C @ 5 V, 225 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.
