RF Dummy Load 150W DC-2.5Ghz 50 Ohm

I decided to create a dummy load for my VU transceiver TM-D710E. After much thought I ended in something simple and cheap using the following minimum materials:

  1. DUMMY LOAD RESISTOR HYBRID TERMINATION 150W 50Ohm DC-2.5Ghz 150N50 (Thanks SV1BDS for usefull advice)
  2. N Type jack female 4 Hole panel Mount Jack with solder post RF connector THIS ITEM IS CRITICAL
  3. Heatsink 20cm x 9.5cm with one side flat and the other with mid flat zone 3.5cm minimun
  4. Thermal grease paste
  5. Nuts and bolts 3mm diameter (4 ps) ≤10mm length

Opening the holes on the heatsink will be done according to the following diagram:DUMMYLOAD-MINIMAL
