Help identify SMA connector

Jan 27, 2011 6 Replies

A coworker came to me today looking for some SMA connectors that mounted on a circuit card, an evaluation board. They were quite different than what I have on hand. The base flange was larger probably 400mils with the four corner pins on a larger spacing about



300mils. The center pin was significantly smaller, perhaps 20mils diameter. Anyone here know a source of these launchers?

Thank you. al


Gotta launch an investigation.

SMA is SMA. SMB is SMB. It is what it is, and if it ain't those, it is some other HF coaxial connector form factor. SMC, SMZ, SSMB, MCX, FAKRA SMB. De list, she goes on...

Take a look at some connectors on a site where they are sold, and see if you see your style there.

I see a bunch at Newark:

Have you asked the company that made the evaluation board? Or even looked at the B.O.M. for the board?

You can't fix stupid. You can't even put a band-aid on it, because it's Teflon coated.

The reduced diameter of the centre pin suggests that it might be a 75R SMA connector, rather than the regular 50R. I didn't know that they existed, but google does

You may have some trouble finding out who sells them.

You might try Pasternack. They carry just about everything.

is the first twelve of 38 possible alternatives.

Some of them do have the smaller centre pin.

If you want to support spammers, that is.
