22708

• 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

• Individual reverse input testpoints and input pads for both the Main and Aux 

reverse inputs 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 ensures hybrid protection without fuses or other 

nuisance failure-causing devices

The Type 2A-2 RF amplifier module
offers a high performance design
solution for the latest HFC networks. 

This amplifier module comes pre-
configured with interstage equalizer,
diplexers, reverse amplifier, and AGC
module, in order to achieve optimum
station performance. Additionally,
maximum flexibility in reverse signal
path alignment is achieved via
individual reverse testpoints and
plug-in pads for each of the reverse
inputs.

The Type 2A-2 amplifier module is a
High Gain Dual amplifier which
provides two high level outputs
(bridger level).
