GainMaker High Output High Gain Balanced Triple
(HGBT) System Amplifier 5-85/105-1002 MHz

Description

The Cisco GainMaker

broadband amplifier platform includes a variety of RF amplifiers that address the divergent

needs of today’s broadband networks. All GainMaker amplifiers provide superior 2-way performance and reliability

combined with a user-friendly layout. All share common plug-in accessories and perform to 1 GHz in the forward

path. The System Amplifiers in this family provide multiple forward RF output ports, while the Line Extenders

provide a single forward RF output port.

GainMaker System Amplifiers use gallium arsenic field-effect transistor (GaAsFET) technology in the interstage

and output gain stages for improved distortion performance.

The GainMaker High Output System Amplifier modules are capable of higher output levels than standard

GainMaker System Amplifier modules, and are mechanically compatible with previous System Amplifier II, II+, III,

and GainMaker housing bases. The DC power supply is modular and located in an updated housing lid for easy

access. All GainMaker System Amplifier modules are factory configured with reverse amplifier, diplex filters,

thermal compensation circuit, forward interstage pads, and interstage equalizer to help ensure optimal

performance. Optional single-pilot Automatic Gain Control (AGC) configurations are also available.

The GainMaker High Output High Gain Balanced Triple (HGBT) System Amplifier (Figure 1) has three forward

outputs and is ideally suited for providing high (bridger)-level RF to the feeder network.
