SMA to BNC?

[WBear2GCR]

Ok, what is cheap and gets me from a female (outside threaded) SMA to a female BNC??

I have one of these SOFT66AD boards (thanks Guy!) and it needs for me to get from the little SMA to something I can actually put some co-ass onta, soze I cudbee uzin eet!

I may have to look at some HP scope boards I have hanging about, maybe those are SMA with little coax on 'em but my recollection is that they are even smaller than this one... and maybe a one piece solution is better... gonna stuff this into a tiny box and see if it works on my larftop and be able to use it portable if nothing else...

Any ideas? Remember I bee cheap...

You need an adapter, but not gold plated like this one.

Here is one from Mouser under $5, I think they mail it at actual mailing costs.

Not sure how cheap is cheap but you could use one of these:

and one of these: http://www.alltronics.com/cgi-bin/item/CA910/J/SMA-M-M-Barrel-connector

or go to the next hamfest and probably find exactly what you need.

or . . . find an SMA jumper and put a BNC(F) on the other end. . .  or vice verse. SMAs might have to be pillaged from old LNAs.
If you must buy one new eBay has them pretty regularly eg. http://cgi.ebay.com/BNC-Female-to-SMA-Male-Plug-Coax-Adapter-Connector-NEW_W0QQitemZ270473183519QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item3ef975411f
$2.75 including shipping is not too bad. . . . its 11AM MDT and you have 2hrs to buy it. . .

That one on ebay is goldplated no less.

Thanks guys!

I opted for an onshore source from ebay, figured the response time from HK might be longer, and ended up pulling the trigger for 4 pcs, final price inc ship-ping was 12 bux... so should be ok!

Now if I can get the software to load...

Now that Bears needs are met I would like to know where I can get pre made coax cable in about a 4-6 foot length or longer with the SMA connectors already on the ends? I don't know what that 1/8 to 3/16 diameter coax is called?

Here is a page at Mouser with cable assemblies, I like them because they don't rip you off with shipping and handling:

http://www.mouser.com/Wire-Cable/Cables-Cable-Assemblies/_/N-5gh1?Keyword=rg-174&FS=True

The flexible cable is usually RG-174.   Rigid, miniature hardline is usually called .141 coax.

Hi Terry,
Yep, either of the cited sources are good. If you can use the RG-174 that's probably the most flexible if somewhat lossy. Maybe at HF the loss is not really significant. If you are going to go any more than a jumper think about using LMR240 Ultra. It's just under a quarter of an inch and has better specs than RG-8X at 1.3dB/100' at 30MHz and it will handle 1490W. Yeah, ~1.5KW in a quarter inch. If you are using an SMA you won't be at this level anyway. . . .You also might consider larger diameter coax if you will be shifting jumpers around as .174 jumpers tend to be a bit fragile on my bench. . .
