Johnson / Cinch Connectivity Solutions SMA Self-Fixture End-Launch Connectors
Johnson / Cinch Connectivity Solutions SMA Self-Fixture End-Launch Connectors overcome the problematic gaps and RF path issues associated with inconsistent soldering processes. These connectors use a proprietary design to accurately align and hold the center contact to the circuit board plane without the need for special fixtures. Special connector legs tightly grip the center contact to the circuit board plane through the complete soldering process, allowing for consistent soldering work on a variety of PCB thicknesses. These connectors also eliminate poor connections that degrade signal quality.
Johnson / Cinch Connectivity Solutions SMA Self-Fixture End-Launch Connectors feature contacts and insulator material that form an optimized connection point. The contact maintains proper impedance under aggressive torque and axial stresses, while the insulator acts as a seal by compressing itself into the board edge during soldering. This creates a barrier between the inner and outer conductors and protects against solder bridging. The design allows the connectors to offer optimal return loss values for frequencies up to 26.5GHz.
These connectors are ideal for reducing the complexity of circuit board systems by eliminating the need for mounting screws, adapters, aftermarket tools, and more.
