FEATURES
• 60 and 90 V AC powering capability
• 15 ampere current capacity (steady state) and 25 ampere surge survivability
• Integrated reverse amplifier, with optimized diplex filter group delay for 
forward and reverse paths
• Reverse input test point and input pad allowing optimum reverse path 
alignment
• Improved station frequency response
• Unitized design (amplifier and power supply in a single module) enabling 
simplified and faster maintenance
• High efficiency, transformerless power supply lowering system operating cost
• Directional Coupler RF testpoints provide optimum accuracy
• Surge Resistant
Circuitry ensuring hybrid protection without fuses or other 
nuisance failure causing devices
DESCRIPTION
The Type 3 RF amplifier module
offers a high performance design
solution for the latest HFC networks. 
The amplifier module comes pre-
configured with interstage equalizer,
diplexers, reverse amplifier, and
either AGC for a 3A, Thermal for a
3T, or jumper for a 3M module, in
order to achieve optimum station
performance. Additionally, maxi-
mum flexibility in reverse signal path
alignment is achieved via the reverse
test point and plug-in pad for the
reverse input.
The Type 3 amplifier module pro-
vides one (bridger level) output.
