Does anyone have any experience with adapters sold on Amazon by Custom Cables Group, LLC? I've asked Custom Cables for specs, but not heard yet because of the weekend. When I asked about brand I was told "generic" which doubtless means China. L-Com has a lot of stuff made in China as do other companies. I don't want to buy parts rejected by a reputable company.
Aaren Technology in the UK makes them and sells them for $111 US each for a pair. They are specified as VSWR < 1.10 to 18 GHz. These are for the 85046A S parameter set for my 8753B VNA.
I've got an 8560A with TG, so I can sweep them over most of the range of the 85046A, but I'd prefer to avoid having to return stuff.
