Abstract:
Connectors significantly influence the total signal transmission on printed circuit board tracks.
Experimental results for standard and modified SMA connectors are presented, based on measurements with
a vector network analyzer up to 18 GHz. The central pin plays an important role, as it causes a resonant
signal reflection near 10 GHz when used at the manufactured length. Reduction of the length (backdrilling)
shifts the resonance to higher frequencies and diminishes its amplitude. 3D-simulations show a good
agreement between the calculated transmission parameters and measurement results. Crosstalk
measurements show the advantage of the shielded track over the traditional microstrip lines.
