SMA - 50 Ohm Connectors
End Launch Connectors - A Johnson Original
INCHES (MILLIMETERS) • CUSTOMER DRAWINGS AVAILABLE ON REQUEST
The End Launch connector is attached to the circuit board
by inserting the board edge between the legs and solder-
ing the legs and center conductor 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 properly 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
