Very good. I did the quick and ugly and so my performance is the other extreme.?
3.5 mm panel mount connectors arranged as suggested earlier, 2 parallel 100 ohm?
carbon film, 1.8w axial R's and measured at the sum port. The center pins were not?
filed flush to the coax launch as I needed the connectors in another project. Bottom line...not pretty, however,?
1 GHz: 18 dB return loss
2 GHz: 13 dB?
3 GHz: 10 dB
Hence, useful to 1 GHz, but obviously a few significant items can get you 10 dB improvement with minor effort.?
So 20 dB at 3 GHz should be a goal and does require some care.?
