Triple System Amplifier
Triple System Amplifier
Consumer bandwidth demand continues to grow at a rapid rate every year. As a
result, cable operators with DOCSIS-based equipment will need to future proof their
networks. They want to plan for reduced service-group sizes and ultimately double or
quadruple (or more) bandwidth speeds. The Cisco 1218 MHz GainMaker
result, cable operators with DOCSIS-based equipment will need to future proof their
networks. They want to plan for reduced service-group sizes and ultimately double or

®
High Gain
Balanced Triple (HGBT) System Amplifier helps to make these demands a reality. The
Cisco 1218 MHz HGBT amplifier provides three high-level forward RF outputs (main
and two auxiliary).
Cisco 1218 MHz HGBT amplifier provides three high-level forward RF outputs (main
and two auxiliary).
Cisco 1218 MHz GainMaker system amplifier modules have increased gain to allow drop in for 750, 870, and 1002
MHz spacing, and are mechanically compatible with previous Cisco GainMaker, System Amplifier II, II+, and III
housing bases, often allowing upgrades to higher bandwidth with no respacing or resplicing. The DC power supply
is modular and located in an updated housing lid for easy access. All Cisco 1.2 GHz GainMaker system amplifier
modules are factory configured with reverse amplifier, diplex filters, thermal compensation circuit, forward
interstage pads, and equalizer to promote optimal performance. Optional single-pilot automatic gain control (AGC)
configurations are also available.
Features
●
High-performance Gallium Nitride (GaN) gain stage technology.
●
Plug-in accessories that are common to all Cisco 1218 MHz GainMaker amps and Cisco GS7000 products
(that is, attenuator pads, diplexers, and crowbar).
●
Amplifier housing that provides access to RF test points without opening the housing.
●
Spring-loaded seizure assemblies allow coaxial connectors to be installed or removed without removing
amplifier RF module.
●
Power supply mounted in housing lid for efficient thermal dissipation (60- and 90-VAC powering capability).
●
15A current capacity (steady state) and 25A surge survivability.
●
Optional three-state reverse switch (on/off/-6 dB), which allows each reverse input to be isolated for noise
and ingress troubleshooting (status monitoring required).
●
Quadrature amplitude modulation (QAM) and analog pilot AGC available (optional).
●
AGC with thermal backup, which eliminates disruptive RF output variation in the event of pilot loss.
●
Reverse input pad and RF test point for each reverse input port to allow optimum reverse path design and
alignment.
●
Surge-resistant circuitry that helps ensure gain stage protection without fuses or other failure-causing
devices.
