what size end launch SMA would best fit a 1mm FR4 board that goes to microstrip? I looked at an SMA datasheet and looked at the end size and it was 0.037 + and - 0.003 as shown here on the dimensions of the SMA connector: https://imgur.com/a/Zi3ZI2r ... would this be a good fit, or what size would you pick for a 1mm sized FR4 board? It comes out that 1mm is 0.039'', but if I get my board manufactured, they might say the SMA does not fit, what size would you pick? I was thinking if the SMA is too large, this could effect the characteristic impedance when it is soldered onto the board, correct?
