Default BNC male to BNC male adapter

I am trying to find a BNC male to BNC male adapter with teflon insulation. All the ones I find have Delrin. I did find one supplier for adapters with teflon insulatin, but they want a $50 minimum order. Anyone know of a supplier who will supply just one? Thanks

That's a tough one. The male to male BNC is rare, don't think I've ever seen one. The Female-female BNC barrel is much more common.
Makertek sells them, but no specs.

I may just have to spring for the $50 minimum, but I really do not want to. But at least I know I am getting what I want. Regards

What you gotta do? I can't picture what you'd use it for. Unless you have a cable with a female end that you need to turn around.

It is to mate a jitter reduction device directly to a DAC input. It's to keep cable induced jitter to a minimum. Regards

Got it, makes sense thanks! A BNC cable without the cable.

Narda? Pasternak? MCM (I think it is)?

Why don't you want to use the ones with Delrin?

How fast is the DAC receiver? Provided your connection transit time is significantly shorter than the receiver response time it should not matter how much shorter it is. There is an argument that a longer cable can reduce jitter, because it gives more attenuation of reflections.

Ideally, your jitter reduction device should be next to the DAC on the same PCB. Even then you have PCB traces acting as transmission lines.

As long as the impedance is 75 ohms, why on earth would Delrin be a problem? It's mechanically much sounder than Teflon.

BNC only works up to 3GHz, so obviously marginal for audio. Maybe we should start a trend to SMA (10GHz)?
