Cisco GainMaker High Output High Gain Balanced
Triple 1 GHz System Amplifier 5-85/102-1002 MHz

Consumer bandwidth demand continues to grow at a rapid rate every year. As a
result, cable operators with DOCSIS

-based equipment have begun introducing fiber

deeper and deeper into the network. They want to reduce service group sizes and
ultimately double, triple, or quadruple bandwidth speeds. The Cisco

GainMaker

GaAs High Gain Balanced Triple (HGBT) System Amplifier is ideal for deep fiber
applications. With higher output levels, up to 56 dBmV, and significantly improved
linearity and performance, this amplifier meets longer reach needs. The GaAs also
continues

Cisco’s legacy of simple, reliable and fast installation and setup. What’s

more, the Cisco GaAs HGBT System Amplifier scales to meet the needs of the HFC
network architecture (one product for all amplifier applications).

The amplifier provides three high-level forward RF outputs - main and auxiliary. All Cisco GainMaker products

share common plug-in accessories and perform to 1 GHz in the forward path. The system amplifiers in this

portfolio provide multiple forward RF output ports while the line extenders provide a single forward RF output port.

Cisco GainMaker 1 GHz system amplifier modules have increased gain to allow drop in for 750-MHz spacing and

are mechanically compatible with previous Cisco GainMaker System Amplifier II, II+, and III housing bases, often

allowing upgrade 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 GainMaker 1 GHz 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.
