| Oct 9, 2015 at 18:53 | comment | added | FullmetalEngineer | Agreed! I'm just getting into RF layout and there are so many little tips and tricks that can make or break your final board. Copying the recommended layout is the way to go especially in my case where I don't have time to respin the board. | |

| Oct 9, 2015 at 17:54 | comment | added | Doov | @pikafu That seems like a reasonable alternative and I have to imagine it would work fine. That stated if they're suggesting a certain layout why not just go for it? I've only done a handful of RF heavy boards (and I'm not an "RF guy"), but every time it feels like there's an element of black magic (I'm exaggerating a bit). I'd personally prefer the "brain off" approach and just copy their suggestions so I could sleep well knowing that at least that part of the design should work properly :) | |
| Oct 9, 2015 at 17:33 | comment | added | FullmetalEngineer | That makes sense. They already have some ground pins connected to the ground pours surrounding the rf traces, but none of the ground pins are connected to the ic ground pad. If it were me I would connect the gnd pins to the ic gound pad and not have the awkward corner pads. | |
