These 1.85 mm Edge Launch Connectors are designed to optimize connector to board transitions. The 1.85 mm interface is mode free through 70 GHz. Test boards with microstrip and GCPWG are available to verify product performance.
These boards are made with an FR-4 stiffener and only the top ground of the board is used for the board transition. No soldering is required so solder is not a factor in interfering in the transmission line.
