Circuitry ensuring hybrid protection without fuses or other 

nuisance failure causing devices

The Type 1A 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 1A amplifier module is an
Unbalanced Triple amplifier which
provides one main (trunk level)
output with two auxiliary (bridger
level) outputs.

NOTE: The output tilt referenced in this document is defined as a LINEAR output tilt (as opposed to a CABLE output tilt). The distortion
and noise figure specifications are applicable across the full operational temperature range (as opposed to being referenced to 68

°

F).  

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).
