This connector is an economical alternative to other high frequency designs in the industry. This patent
pending design differentiates itself from other launch connectors:
• Design of the connector is self contained, no external mounting screws, adapter sections, spring
• Center contact pin does not require special orientation to the surface of the circuit board. The cen-
• Output coax of the connector at board launch is sized appropriately to match the thickness of the
• Signal side grounding legs of the connector are spaced close enough to keep grounding paths
• Signal side grounding legs and GCPW geometry control radiation, no additional shielding is
• Connector is not locked into position when placed on the circuit board. Intentional floating design
• The new distinctive through hole mounting technique allows the use of one connector with varying
• A small amount of PTFE insulation projects from the rear mating plane of the connector, acting as
• Appropriate sized connectors do not require additional compensation to standard coplanar or
clips, etc. are required for assembly to the circuit board.
ter contact is mechanically captivated and optimized to maintain proper impedance while with-
standing torque and axial force stress.
high frequency board substrate. The output coax section extends well within the connector while
maintaining constant inner and outer coaxial diameters.
short, but far enough apart to maintain constant impedance in the launch transition area.
required to prevent signal cross-talk effects in the transition area. The launch transition is effec-
tively isolated from adjacent transmission lines in the signal plane.
allows proper alignment in X, Y and Z, minimizing discontinuities due to manufacturing tolerances.

launch design, which was pioneered by Emerson Network Power Connectivity Solutions over 20
years ago.
a seal when soldering the center conductor pin to the trace. The connector is held against the cir-
cuit board edge during the soldering process, compressing the PTFE insulation. This effectively
creates a barrier between the inner and outer conductors, preventing the bridging of solder.
microstrip matched impedance line geometries. Transition can be fine-tuned by pulling the trace
