SMAs are fine up to 12 GHz or higher. Other factors might be size, environment, etc. you have a lot of connectors to choose from

it really depends on your requirements. There's no way anybody here can tell YOU what YOU need. I don't understand your confusion. If you can use a vertical, through-hole part, then use it.

Your Right Barry. It returns to my limitations. I'm not familiar with specific functionality of every kind of SMA connector. for example whats the deference's between bulkhead and straight Types?
I should place my design in Metallic House so it seems i can't use R/A or End launch?. so I think my only choices are straight and bulkhead!
sorry if my questions are so cheap. by the way Thanks

If think about transmission line discontinuities, you'll notice that edge mount SMA (end launch) is preferable.

In fact your right. but when there is Metalic Housing it cause some problems.
it seems Panel ones are better choices.
