SMA Connector for soldering

Hello,

I have to build an antenna to make some experiment.
The antenna will be connected to a circulator with SMA-female end.
Could you suggest me a connector able to link the antenna with the circulator?
Please note that my idea is to solder directly the homemade antenna with the connector...

Thank you very much

I don't have information about your antenna configuration but why don't you put SMA male directly on your antenna?

Is a normal circolar loop antenna, freq range 2-4 GHz...
The circulator has a SMA female end so a need a connector, I was just thinking about a SMA female to SMA male, but when i called the provider (minicircuits), they suggested me a special suitable connector for soldering that they are not providing and they cannot tell me where to buy...
That′s what they wrote:
"I would recommend selecting an appropriate SMA connector that is specifically designed to be soldered / fixed to an item such as a cable assembly / PCB / antenna etc.
Mini-circuits does not supply such connectors."
Then he suggest:
"I searched for PCB mounting connectors since the pins may make it easier to solder the connector to an assembly such as an antenna or perhaps to an interface PCB assembly. However, there are other connectors like this available (e.g. ones intended to be used in cable assemblies), these may be better suited to your specific application (it will depend on the configuration of your antenna)."
Can yo explain me how this connectors work?

Yes, of course you have plenty of SMA connectors : PCB mount, flange, surface mount, socket or plug... depends on your circular loop antenna.

Show us your antenna I/O

I haven′t any picture yet of the antenna!
I have to build it, besically u can think about it as a copper looped wire..
My supervisor told me to solder it directly to the connector and do some tests(connecting it and try some signal, I need it to heat up nanoparticles with induction heating), that′s why i need to know if this is a rough but correct way to start and if it exist a particular-simple-soldering connector.

Why not, you can try with the sodering iron that should work. You might use a BNC connector instead of, this is bigger and easy to solder and connect it to the circulator with a BNC/SMA coax cable or BNC/SMA adapters.

So, you mean something like this:
SMA Jack to BNC Jack, Straight Adaptor
Can i solder directly the antenna to the male end of the BNC?
What is the difference between this end and the SMA, I mean, why not using a SMAmale-SMAmale then?
I was thinking that were existing some connector really suitable for soldering, i mean something like with a long tip..but that was just a supposition, I′m not an expert..
thank you so much

Maybe this can help you :

Teleg?rtner - Karl G?rtner GmbH | Coax- und DataVoice-Produkte

Telegaertner has long tip SMA connector for soldering .
They doesnt come cheap but are of good quality .

If your antenne is needed to heat up particles are you sure that an SMA connector can handle the rf power ?

Hi,
I just got a reply from a supplier, he suggested this
Digi-Key - ACX1429-ND (Manufacturer - 132145)
That in fact look really much like the one that you just suggested me.
He also suggested this one:
Digi-Key - CONSMA013.031-ND (Manufacturer - CONSMA013.031)
Could you please explain me where is the difference?

The one with the long lead is meant for chasiss mounting where the central pin passes trough the material of the box . The teflon dielectric surrounding the central pin causes a 50ohm coaxial line trough the wall of the box .

The one with the short lead is for mounting on a PCB trough hole .
