The project idea is to design and build a Triplexer  for 2000-3000 watt output power which is smaller than the 3000W  version of the Triplexer.

It is almost the same schematics  I used for 3000W version but with some improvements made for some parameters.  The Triplexer is built on a PCB boards.

2000W High Power Triplexer General Specification:

  • Insertion Loss                        < 0.1 dB
  • Band Port Isolation              > 30 dB (see graphs below)
  • Return Loss                             > 26 dB

 Recommended Output Power with antenna VSWR < 1.5

  • 2500W CW/SSB to any band port with one signal at a time (SO2R category)
  • 2000W to every band port when two or three bands used the at same time (M2 / MM category)
  • Enclosure is 1444-1783 from Hammond
    • Without Fan – 17”x 8”x 3″ 

Triplexer build on three boards for each 10, 15 and 20 meter bands.

Each band triplexer section built on a PCB board and inside the enclosure all boards separated by an aluminum shields. 

Below, is the triplexer before going to a final adjustment stage.
