Withwave announced that New 1.85 mm Wave Launch Connector (67 GHz).
It's specially designed for well-used high frequency substrate to minimize electromagnetic effects including impedance discontinuities from coaxial to microstrip structure.
The test result shows that good return loss performance up to 65 GHz test freq. range on Duroid 5880 substrate (5 mil. thickness)
