RF noob question: SMA port savers: from where do you get them ?

[rteodor]

Got tinySA/LiteVNA for fun but I connect and disconnect them more times than I expected.

I checked the usual places from where I get stuff (Mouser/Eleshop/Reichelt/even Amazon) but either I am too dumb or they are not there.

So, where do you find this SMA port savers ?
(with bonus thanks for places that might have other GHz RF'ies like mixers and filters )

Looking at the price I remember how I did not find them on Mouser. Sometimes the subconscious decides...

Haven't tried them, but I could only find 90 degree Angle on Amazon for Chinesium parts :

For straight through Chinesium, would need to use Aliexpress or similar I think.

Bit of a crapshoot how it will perform though in the couple GHz range.

Also risk damaging connectors on other devices, as their interpretation of the tolerance specs on connectors tends to be quite loose...

I bought mine off eBay.  I have tried several different types and they all work well (only tested to 900 MHz.)  You can get them from Digi-Key but way more expensive.

Just the domestic RF FM up to 2.4GHz. I'll save fine radar applications for another life.

Good point. I also got some not so cheap atenuators that in total were more expensive (~100EUR) than the tinySA (~50EUR).
So to protect the atenuators now I need the expensive port saver ? Wouldn't be better to just get some quality cables instead and leave them connected ?

Minicircuits is my go to for most connectorized components.

Sf-SM50+ go for ~$11.

I couldn't be happier.  These are probably overkill for a budget nano, but I am certainly happy with these!!!
