Features
●
High-performance GaN gain stage technology
●
Plug-in accessories that are common to all Cisco GainMaker nodes and Cisco GS7000 products
(i.e., attenuator pads, equalizers, diplexers, and crowbar)
●
Amplifier cover that provides access to RF test points
●
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) that 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
