I'm implementing a TI reference design for their CC2500 radio chip using a chip antenna. From the reading that I've done, I surmise that I will need to do final matching of the antenna to the balun after setting the board into its final plastic enclosure. I have a rough idea of how to do this using a network analyzer and swapping out components on a final Pi matching network. However, my dilemma, hence my question, is how do you hook a network analyzer up to a device? Most analyzers I've looked at use N-type or SMA connectors. I don't really want to spin a second board with SMA connector pads coming off the antenna feed trace. Even if I did do that, wouldn't they change the line impedance to some degree? Is there some sort of RF probe you can use to check the traces directly without using some matching connector? Please help. Thanks! I didn't find the right solution from the Internet.
