SMA High-Frequency End-Launch Connectors Johnson / Cinch Connectivity Solutions SMA High-Frequency End-Launch Connectors can be used on high-frequency PC board substrate layers as thin as 8mm and operate at frequencies up to 26.5GHz. These connectors provide a solution for microwave engineers who fabricate circuit designs on ultra-thin high-frequency board substrates. The in-line connector design has fewer reflections compared to a right-angle (perpendicular) PC-mount transition. Johnson / Cinch Connectivity Solutions SMA High-Frequency End-Launch Connectors offer 50Ω impedance and 1000MΩ minimum insulation resistance in a temperature range of -65°C to +165°C. Ideal applications include amplifiers, antennas, converters, radar systems, high-speed routers and switches, automated test equipment, RF identification tags, and more.
