I have NOT been able to find a standard for SMA PCB Connectors - Do not think it exists because it can not comply with specs for 18GHz
For monitoring we chose a small plug that was suitable for coax - SMA suited us well and could be cheap.
I do not know where Egon buys connectors - A German supplyer I suppose.
I find mine on eBay at very low prices - NO one have failed so far (7-9-13)
For example http://www.ebay.com/itm/PCB-Mount-SMA-Fe...hTkQ4rJzUg
or http://www.ebay.com/itm/5pcs-PCB-PC-Boar...xy7odRy5os
