Solderless coaxial sockets offer reproducible transmission quality for high frequency lines

Würth Elektronik has expanded its SMA connector family for high-frequency applications, including WR-SMA PCB Solderless. The solderless approach enables quick and easy assembly without damage to the PCB. Besides simplifying the installation process, which needs no soldering equipment, the solderless SMA connectors can be re-used multiple times, making them ideal for prototyping or temporary use. This makes them an affordable solution for efficient testing. What is the biggest advantage of these sockets? Because no solder is needed on the signal pin, reproducible connection quality is achieved, and impedance variation due to the amount of solder paste is avoided.

The company has opted to use brass instead of stainless steel for its connector family, which differs from many competitors by supplying a cost advantage while maintaining the same electrical performance. The screwed clamp connector provides a highly robust mechanical connection. Additionally, the solderless coax connectors allow for easy repairs and hassle-free replacement in the field without needing special tools or knowledge. The SMA sockets are suitable for strip and multistrip lines and coplanar waveguides.

As the SMA interface complies with the MIL-STD-348 standard, is designed for 50-Ohms, and supports up to 27GHz, the solderless coax connectors are particularly suited to high-frequency PCB applications that need precision. The connectors are recommended for test equipment, evaluation boards, and applications with an operating temperature range from -65C to +165C.

The company offers free samples for developers looking to use these connectors in telecommunications, broadband, and antenna-related wireless applications or testing equipment.
