Cisco Cisco 1 GHz GainMaker Amplifier Fiche De Données
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 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 now 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 Unbalanced Triple System Amplifier is ideally suited as a trunk/bridger amplifier. The
Unbalanced Triple provides one low level RF output for the trunk (express) path and two high (bridger) level RF
outputs for the feeder network.

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