The amplifier consists of 10 interconnected modules.  Each module is (as much as possible) independent of the others up-stream and down-stream from it, so that modules can be swapped out and replaced as new (or other) options become available.  For example, we expect to offer both a basic 5 pole Butterworth output filter board, and a more complex and expensive diplexer filter board - each builder can choose which to install. 
The modules include:
  • Input / Output board
  • Input attenuator
  • RF Splitter
  • RF amplification modules
  • Output combiner
  • Output filters
  • Microprocessor controller
  • DC input board
  • Cooling system
  • Chassis and mechanical system
