The Johnson High Frequency End Launch connectors are patent pending and designed to transition microwave energy from coaxial to planar transmission line structures. They provide a unique solution for microwave engineers fabricating circuit designs on thin, high-frequency board substrates. The in-line connector design minimizes reflections, making it ideal for applications such as cellular linear power amplifiers, microwave filters, and wireless infrastructure antennas. The connector's design eliminates the need for external mounting screws and adapters, simplifying assembly and ensuring proper impedance matching.
