Description
The MAAMSS0042 CATV amplifier is a GaAs MMIC
wh i c h e x h i b i t s lo w d i s t o r t i o n in a
lead-free miniature surface mount plastic package.
The MAAMSS0042 employs a monolithic single
stage design featuring a convenient 75 Ω input/
output impedance that minimizes the number of
external components required.
The MAAMSS0042 provides low noise and high
linearity. It is ideally suited for set top boxes, home
gateways, FTTX, Drop Amplifiers, and other
broadband internet based appliances.
The MAAMSS0042 is fabricated using M/A-COM’s
PHEMT process to realize low noise and low
distortion. The process features full passivation for
robust performance and reliability.

* Restrictions on Hazardous Substances, European Union Directive 2002/95/EC.
1. Reference Application Note M513 for reel size information.
2. All sample boards include 5 loose parts.
3. Exceeding any one or combination of these limits may cause
permanent damage to this device.
4. M/A-COM does not recommend sustained operation near these
survivability limits.
5. These operating conditions will ensure MTTF > 1 x 106 hours.
6. Junction Temperature (TJ) = TC + Өjc * (V * I)
Typical thermal resistance (Өjc) = 59° C/W.
a) For TC = 25°C,
TJ = 57°C @ 5 V, 110 mA
b) For TC = 85°C,
TJ = 115 °C @ 5 V, 100 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.
