Description
M/A-COM Tech’s MAAM-008970 2-way active
splitter is a GaAs MMIC which exhibits low noise
figure and distortion in a lead-free PQFN plastic
package. The MAAM-008970 employs a low noise,
high linearity amplifier and power splitter
functionality. The design features 75 Ω inputs and
outputs.
The MAAM-008970 is ideally suited for satellite
communications multi-tuner set top boxes, and other
broadband based appliances.
The MAAM-008970 is fabricated using M/A-COM
Tech’s PHEMT process to realize low noise and low
distortion. The process features full passivation for
robust performance and reliability.

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.
4. Exceeding any one or combination of these limits may cause
permanent damage to this device.
5. M/A-COM does not recommend sustained operation near
these survivability limits.
6. These operating conditions will ensure MTTF > 1 x 10
6
hours.
7. Junction Temperature (T
