Hi all.
I am designing a PCB where I want to use SMA (SMA to U.FL) Antenna Connector for SIMCOM SIM908 Module. My Schematic is attached.
I would like to have your advice regarding RF PCB design ...
- The SMA Connector is 5 PIN. Where one is Signal PIN and other four PIN's, I used as GND. Is it Ok? Or I need to Keep that PIN's open?
- For PCB design what Trace Width, Clearance are recommended for RF connection?
- At Datasheet its mentioned that the Trace needs to be 50Ohm? How can I understand the Impedance is 50Ohm?
- If I use GND Plane (Both TOP and Bottom, will it make problem for RF Trace?
- Will it be a problem if the RF Trace Layer changed with VIA?
Regards.
