Circuitry ensures hybrid protection without fuses or other 
nuisance failure-causing devices
DESCRIPTION
The System Amplifier III (SAIII)
family of RF amplifiers includes a
variety of gain, output and frequency
configurations to optimally address
the various network architectures
being deployed.  All SAIII amplifier
modules offer 15 amp current
carrying capacity, and come pre-
configured with diplexers and
reverse amplifier for optimum
reverse performance.
The SAIII Unbalanced Triple - RC
(Reverse Conditioning) amplifier
module incorporates all of the
features of the SAII+ Unbalanced
Triple.  Additionally, maximum
flexibility in reverse signal path
alignment is achieved via the
incorporation of individual reverse
input testpoints and pads for each of
the reverse inputs.  
The Unbalanced Triple - RC amplifier
module can be field configured with
a variety of standard accessory
options to meet specific
requirements.
• For applications where output level
control is not required, the 
interstage is typically configured 
with a stand alone Interstage 
Equalizer (ISEQ).
• For basic output level control in 
aerial plant applications, a 
combination Thermal
Compensator/ISEQ is available.
• For the most accurate degree of 
level control in both aerial and 
underground plant, a combination 
AGC/ISEQ is the desired option.
The Unbalanced Triple - RC provides
one low level output (trunk level)
and two high level outputs (bridger
level).
