Created: Sep. 2019

Fig. 1 SMA edge launch jack receptable prior to mounting on PCB

Fig. 2 Top-side of SMA connector. As usual, the top-side's ground prongs are soldered to the PCB ground

Fig. 3 Bottom-side of the connector. Not only are the prongs soldered to the ground-plane, but the entire bottom is covered with solder

Fig. 4 Soldering the bottom prongs improves the insertion loss (black trace) compared to the not-soldered case (pink trace)
