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 Dual (HGD) System Amplifier helps to make these demands a reality. The Cisco 1218 MHz GainMaker^® High Gain Dual (HGD) System Amplifier (Figure 1) provides two high-level forward RF outputs (main and auxiliary), with the option to create a third RF output by using an optional plug-in auxiliary path signal director.

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 1.2GHz 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.
