Up until today i've ezperimented with antennas by basically taping the coax endpoint to my breadboards and it's been working "so so" and I'm looking for a PCB connector for my N Connector cable.

Any ideas what to get and how you connect those? Anything special to consider?

  • \$\begingroup\$ Yea that was a bit more expensive than I would imagine it would be considering the antenna itself cost only 30$, but it would be worth it if i could solder it in place and get rid of disconnects because of the temporary fix i have today.. Ugh, 4 connectors tho? or just soldering points? \$\endgroup\$

  • \$\begingroup\$ @Torxed do you have to use N connectors? \$\endgroup\$ Jul 4, 2013 at 14:03
  • \$\begingroup\$ Are you stuck with using type N? SMA connectors are generally available in the $5 range, but can't handle as much power as type N. \$\endgroup\$

1 Answer 1


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.

SMA edge

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.

n-sma SMA

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.


  • \$\begingroup\$ I'm happy with that explanation! I'll snoop around for a beginner forum but for now, this is just what i need to get started in my understanding of radio tech (been eager to learn this for 15 years now)! \$\endgroup\$
