Hello,  
What are the Types, Brand and Dimensions of the Transmitter and Receiver Connectors?

- PCB side (U.FL-R-SMT-1)?
- Cable side (U.FL-LP Cable assembly)?

Thank you in advance for your answers  
Best regards  
Bernard MALET

Thank you Marty for your information  
I think the type U.FL or E.FL depends on the cable that you want to mount

Bernard,

Just as a follow-up, these same connectors in this EBay listing fit my LimeSDR perfectly and function great - I’ve purchased them twice and there were no issues at all:

[http://www.ebay.com/itm/231357604143?\_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT](http://www.ebay.com/itm/231357604143?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT)

The U.FL connectors that I sent you earlier aren’t that different either - most on EBay will work acceptably.
