TEST DATA:

End Launch Connectors on a Coplanar Board

Below are test results to 50 GHz for two 1492-04A-5 end launch connectors on a .008" Rogers RO4003 coplanar board. The plot shows both VSWR and insertion loss for the test board and the two connectors. Similar boards are used for the other launch geometries.
