[Amps] Dummy Load

[Mark Marsden]

Hi Bert, Ian, David, et al 

I had a look at the datasheet, 3uH is unfortunate.   

Other resistors, for a 30dB T then, are Vishay parts, 47R 500W (FEC 306-8043), then 3R3 to deck, three 50W 10R in parallel (FEC 306-6885), and a 20W 47R (FEC 306-6710) to the output. Then a lab 10dB attenuator.  

That costs £(36.92 + 3 x 3.09 + 2.24) = £48.43, plus junk box heatsink fan & connectors. Another way, about the same cost, is a MFJ-250X and a Breune coupler.
