The Johnson High Frequency End Launch connector is designed to transition microwave energy from coaxial to planar transmission line structures. This patent-pending connector provides a unique solution for microwave engineers fabricating circuit designs on thin, high-frequency board substrates. It minimizes reflections compared to right-angle transitions and is suitable for applications like cellular amplifiers, microwave filters, and radar systems. The connector attaches directly to a coplanar waveguide circuit board, operates at frequencies up to 26.5 GHz, and features a self-contained design with optimized impedance and mechanical stability.
