Features 

● 

High-performance Gallium Nitride (GaN) gain stage technology. 

● 

Plug-in accessories that are common to all Cisco 1218 MHz GainMaker amps and Cisco GS7000 products 

(that is, attenuator pads, diplexers, and crowbar). 

● 

Amplifier housing that provides access to RF test points without opening the housing. 

● 

Spring-loaded seizure assemblies allow coaxial connectors to be installed or removed without removing 

amplifier RF module. 

● 

Power supply mounted in housing lid for efficient thermal dissipation (60- and 90-VAC powering capability) 

● 

15A current capacity (steady state) and 25A surge survivability 

● 

Optional three-state reverse switch (on/off/-6 dB), which allows each reverse input to be isolated for noise 

and ingress troubleshooting (status monitoring required) 

● 

Quadrature amplitude modulation (QAM) and analog pilot AGC available (optional) 

● 

AGC with thermal backup, which eliminates disruptive RF output variation in the event of pilot loss 

● 

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

alignment 

● 

Surge-resistant circuitry that helps ensure gain stage protection without fuses or other failure-causing 

devices.
