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

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.

When calculating end of line performance, the specifications used for all of the amplifiers in a given cascade must be of similar format,
due to the fact that all amplifiers in a cascade must operate with a similar output tilt (either all LINEAR output tilt or all CABLE output tilt).
