DESCRIPTION
The Type 1A RF amplifier module
offers a high performance design
solution for the latest HFC networks.
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.
