DESCRIPTION
The System Amplifier III (SAIII)
family of RF amplifiers includes a
variety of gain, output, and frequen-
cy configurations to optimally
address the various network archi-
tectures being deployed. All SAIII
amplifier modules offer 15 amp
current carrying capacity, and come
preconfigured with diplexers and
reverse amplifier for optimum
reverse performance.

The Low Gain Dual provides two
high level outputs (with the capa-
bility to split one to feed a third port)
and is primarily utilized in advanced
Fiber-to-the-Serving Area (FSA)
architectures functioning as an
express or tap amplifier. It can also be
deployed as a terminating bridger in
more traditional architectures.
