SMA - 50 Ohm Connectors
End Launch Connectors - A Johnson Components TM Original
The End Launch connector is attached to the circuit board by inserting
the board edge between the legs and soldering the legs and center con-
ductor to pads on the board. For optimum high frequency performance,
the connector to circuit board transition must be adjusted for low VSWR.
To compensate for the transition from coax to microstrip, trace widths “A”
and “B” must be adjusted based on circuit board thickness. When prop-
erly adjusted, this technique yields a low VSWR over a wide bandwidth.
The tabulated dimensions "A", "B", "C", "D", and "E" were determined
experimentally to achieve low VSWR (typically less than 1.5 up to 18
GHz). The circuit board used for these tests was double-sided FR 4 with
1 oz. copper on both sides. The copper was left on the bottom of the
board to create a ground plane for the 50 Ohm microstrip structure. While
not all inclusive, these dimensions are given as reference information for
selected SMA End Launch connectors. Further adjustments may be
necessary depending upon the application. All dimensions are in inches.
Tabulated Dimensions "A", "B", "C" and "D" are symmetrical about the center line
