TNC connector for PCB at 1.6GHz

[Mikko Syrjälahti]

I'm looking for a way to add a TNC connector to our PCB. The PCB will have
micro stripline or grounded coplanar waveguide circuit to which the signal
has to connect. 50ohms as usual.

Most PCB connectors seem to have two wires coming from the end of the connector
and I strongly suspect their matching integrity.

Does anyone know of suitable connector or matching characteristics of the forementioned
type of TNC connectors ?

There are coaxial sockets designed to provide a minimally reflective
transition from microstrip to coxial cable. IIRR TNC connectors are
too big to match to normal thickness PCB's and you'd probably have to
throw in some kind of inter-series connector to get the signal from a
sub-minature coax connector to TNC.

seems to have some SMCC connectors that might do what you want.

Thanks, I'll get a few for testing. In addition I found 31-5660 and 31-5607 from Amphenol.
The AMP connectors seem to have threads for panel nut to reduce PCB strain.

I thought connectors with pigtails and inter-series connector would've been
much more expensive than direct connector. After checking a few on-line quote
systems for pigtails it seems that this method is quite viable technically and
economically. A big plus is also not getting stuck with single supply of exotic
and expensive connectors!

Thank you both!
