RF ESD protection

nicoloquinte

Hi,

I'm entering the beautiful world of RF design, and after looking into the documentation of the ublox NEO-6M module and saw this:

So because i know that my antenna is absolutely perfect (that isn't true but i'm proud of my qfh garbage)

I need to go with the inductance method since some manufacturers are saying that I should not go with a TVS because that's doing Bad things to the signal :

So Do someone have any idea about how I can calculate the inductance

 

(BTW i wont connect my antenna directly to the RF-IN like this , i will do a little step of filtering)

    Actually if the thing has 2 pins I already soldered successfully those tiny packages, my problem is more on ICs.

    And i don't think I'm overthinking It, my antenna has a connector on it and I already the cables.

    I'm only 17 so that's hard for me to buy these easy to make PCBs , $50 is way to much for a simple TVS and connectors but for other cool things like Peregrine Switches maybe  i will by eval boards.

    I'm only a beginner but I try to make really high quality stuff , I plan To make a second and better QFH antenna but the first one was actually quite good.

    Thank you for all the answers, they made me learn a lot
