Cisco Cisco 870 MHz GainMaker Amplifiers Hoja De Datos
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 utilize 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 ensure optimal performance.
Optional single-pilot Automatic Gain Control (AGC) configurations are also available.
The GainMaker High Output HGBT (High Gain Balanced Triple) System Amplifier has three forward outputs and
is ideally suited for providing high (bridger) level RF to the feeder network.

Features
• Capable of higher output levels than standard GainMaker amplifiers
• 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
• QAM Pilot AGC now available in addition to existing analog carrier AGCs
• 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
