Alrighty, now Christmas is done, it's almost time to order the final revision of the PCB's.
I have one last thing to figure out (If it even matters at 3GHz?)
To keep impedances as close to 50 ohms and VSWR low as possible etc etc etc, I have seen that for a through-hole RF connector into a coplanar waveguide, the ground plane should be pulled back around the connector's center pin.
Does anyone know how to calculate the required clearance? I'm using a standard 2 layer 1.6mm FR-4 PCB with 1oz copper.
Here's a picture of the board so far, you can see I pulled the ground plane back by an arbitrary amount to the left of the PCB for now, I just need to get that right and the PCB will be done ready for production.
Thanks!
