High Frequency SMA End Launch Connectors
Design Features
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
clips, etc. are required for assembly to the circuit board.
? Center contact pin does not require special orientation to the surface of the circuit board. The cen-
ter contact is mechanically captivated and optimized to maintain proper impedance while with-
standing torque and axial force stress.
? Output coax of the connector at board launch is sized appropriately to match the thickness of the
high frequency board substrate. The output coax section extends well within the connector while
maintaining constant inner and outer coaxial diameters.
? Signal side grounding legs of the connector are spaced close enough to keep grounding paths
short, but far enough apart to maintain constant impedance in the launch transition area.
? Signal side grounding legs and GCPW geometry control radiation, no additional shielding is
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.
? Connector is not locked into position when placed on the circuit board. Intentional ?oating design
allows proper alignment in X, Y and Z, minimizing discontinuities due to manufacturing tolerances.
? The new distinctive through hole mounting technique allows the use of one connector with varying
circuit board thicknesses. The connectors are also available in a traditional straddle mount end
launch design, which was pioneered by Emerson Network Power Connectivity Solutions over 20
years ago.
? A small amount of PTFE insulation projects from the rear mating plane of the connector, acting as
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.
? Appropriate sized connectors do not require additional compensation to standard coplanar or
microstrip matched impedance line geometries. Transition can be ?ne-tuned by pulling the trace
back a slight amount from the board edge.
