That RF trace looks like it wanders a long way (relatively speaking) before it gets to the SMA connector. It needs to be closer to the RF pin of the radio module to avoid problems.
Rather, it would wander a bit, if it were actually connected...Looks like you got bitten by the eagle "feature" where it looks like a wire is connected, but it isn't actually connected. the RF out isn't actually connected to the radiometrix footprint.
Since you appear to already have your boards fabbed, you can use a short piece of small coax (e.g. RG174) to jumper from the header to the SMA.-j
I'd like to find a pair of connectors I can use to mount the GPS on-board as well as inserting a cable in-between (and something a little more robust than a pair of 0.1" connectors).
do you think it would be wise to increase the size of the RF trace?
QuoteI'd like to find a pair of connectors I can use to mount the GPS on-board as well as inserting a cable in-between (and something a little more robust than a pair of 0.1" connectors).What about a board to board connection, no cable? Samtec makes a 0.1" socket (web site drawing ) that may fit the bill - it would allow that header on the GPS to plug in through the board, so the GPS mounts flat. I don't have any experience with this particular connector, but I've got a device that has a similar 2mm version of this thing, and it makes for an incredibly low profile mount. If you want to break it out, I'd do it by adding a connector to the PCB (if I understand what you're trying to accomplish, that is).
Quotedo you think it would be wise to increase the size of the RF trace? What I know about RF PCB layout would fit in a gnat's navel. If it were me, I'd put the connectors as close together as possible, so that my ignorance had limited impact. :|-j
Where can you purchase SkyTraq SUP500R modules or similar? I am interested in building a GPS project but, I would like to get the parts from someone like Digi-key or Mouser.
Nice work on your project so far!
