First question asked Welcome!
Level 1

The BGSA142GN12 SP4T switch data sheet shows a single RFC pin. However the PCB footprints for the switch show an RFC1 and RFC2 pin. How should these 2 pins be handled? should they be shorted together? should RFC2 be floating? 

 

Thanks!

Hi Annemariez,

both RFC ports are those that connect to the same signal path and are internally connected.

On your PCB design, please connect those 2 ports as well to keep the symmetrie in the connection. Below you find a screenshot of the evaluation board of this device family.
