Lime mini : What is the maximum input power acceptable on the TX connector?


I’am looking for the maximum signal power that is acceptable on the TX connector.
Of course it’s not at all a good idea that a signal is sent to it, because it’s an output, but it can happen if my external TX/RX switch leak or have a problem, so it would be really nice to know at witch level the board is damaged.

Thank you for your help
