N Connector - Best mount for PCB and how?
Just to follow up on the comments.  Most people don't mount a big N connector on a PCB edge because it would flex the PCB too much.  Inside an enclosure you could mount the the N on a panel then cable over to the PCB.  An edge mount PCB SMA connector is a good choice, just make sure the gap matches the PCB thickness that you are using.



As mentioned by several people in the comments SMA is usually a preferred option.  They have very high frequency responses to 18GHz (which matches Type-N) and sometimes higher and you can buy good cables for them.  Typical curves for a new clean Type N connector with a perfect load (VSWR=1.0) give limits of ≈5000 W at 20 MHz and ≈500 W at 2 GHz.  Compared to SMA which is about 500W @ 100Mhz and 170W at 1GHz.  

I use them so often I put N-SMA adapters on my equipment and use all SMA cables.




Also for "launching" or tying into a an area of a PCB I use simi-rigid SMA coax.  This is basically a "pipe" where the outside is copper is hard and good for soldering down to the PCB ground plane in either a large area or a few spots.  The center conductor is kept short as possible to get to the test point.  This provides strain relief and a very few reflections across the band to about 6Ghz, sometimes higher if you're careful.
