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® 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 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 allowin g 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.

Quadrature Amplitude Modulation (QAM) 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.
