Hi,
I'm a beginner in the world of the PCB's and of RF. I need your help and your knowledge.  :D

I want to make a PCB with the Quectel MC60E with the two SMA connectors, one for GSM signal, other for the GPS/GLONASS. For the BLE I want to put one antenna on the board like A5839 Antenova (http://www.antenova-m2m.com/wp-content/uploads/2016/01/Rufa-A5837-A5887-PS-1-2.pdf).

I already did my research but I'm a bit confused, I think I only need to take care of the 50 Ohm pad from the MC60E to SMA connector.

My questions are :
- I only need to take care of the impedance matching? What is the best procedure to do that?
-What are the most important things to have a PCB without EMI problems? The PCB will have more components like sensors for example...
 

Thanks in advance
