    Could the 1.27mm RF cable stand for the 6KV contact ESD?

    Hi, All,
    I made a GSM module with 8W output.
    Everything seems ok.
    But when doing ESD 6KV contact test, the module is broken and can't boot up again.
    Now I have not checked the broken module because it is still in the lab.
    The tester told me that when antenna connector being tested ESD, the module is down.
    The antenna connector is TNC, but the innner RF cable is 1.27mm (outer diameter) 50 ohms cable.
    So I doubt if the cable is broken?
    I checked the cable datasheet and haven't found any ESD info.
    Hope you can help me.
    Thanks.
    Best,
    Tony Liu

    ALL
    From LEMO cable, I know the cable operating voltage, U max. KV eff., is about 1KV.
    So 6KV should broke the cable.

    ESD test energy is so low that it can hardly damage a cable.
