Description

The 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 now 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 utilize GaAsFET technology in

the interstage and output gain stages for improved distortion

performance.

The GainMaker System Amplifier modules have increased gain and are mechanically compatible with previous

System Amplifier II, II+, and III housing bases, often enabling upgrade to higher bandwidth with no re-spacing or

re-splicing. 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 equalizer to ensure optimal performance. Optional single-pilot

Automatic Gain Control (AGC) configurations are also available.

The GainMaker High Gain Dual (HGD) System Amplifier is ideally suited for providing high (bridger) level RF to

the feeder network. It provides two forward RF outputs (Main and Auxiliary), with the option to create a third RF

output via use of an optional plug-in Auxiliary path signal director.

Features

• Common RF test points for forward output and reverse injection simplify reverse balancing

• Increased forward gain to facilitate drop-in bandwidth extensions without re-spacing

• High-performance GaAsFET gain stage technology

• Fixed-value, plug-in accessories are common to all GainMaker products

• 60 and 90 volt AC powering capability

• 15 ampere current capacity (steady state) and 25 ampere surge survivability

• Optional 3-state reverse switch (on/off/-6 dB) allows each reverse input to be isolated for noise and ingress

troubleshooting (status monitoring required)

• AGC has Thermal backup, which eliminates disruptive RF output variation in the event of pilot loss

• Improved hum modulation

• Plug-in, self-contained diplex filters

• Modular high-efficiency power supply allows simplified maintenance

• Reverse input pad and RF test point for each reverse input port allow optimum reverse path design and

alignment

• Directional Coupler RF test points provide best accuracy

• Surge resistant circuitry ensures gain stage protection without fuses or other nuisance failure causing devices
