Würth Elektronik expands its SMA connector family for high-frequency applications to include WR-SMA PCB Solderless. The solderless approach allows quick and easy assembly without damage to the PCB. Besides simplifying the installation process, which requires no soldering equipment, the solderless SMA connectors can be reused multiple times, making them suitable for prototyping or temporary use. This makes them an affordable solution for efficient testing. What’s the biggest advantage of these sockets? Because no solder is required on the signal pin, reproducible connection quality is achieved, and impedance variation due to the amount of solder paste is avoided.
Würth Elektronik has opted to use brass instead of stainless steel for its connector family, which differs from many of its competitors by providing 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 the need for special tools or knowledge. The SMA sockets are suitable for both strip and multistrip lines, as well as coplanar waveguides.
As the SMA interface complies with the MIL-STD-348 standard, is designed for 50 ohms, and supports up to 27 GHz, the solderless coax connectors are particularly suitable for high-frequency PCB applications that require precision. The connectors are recommended for test equipment, for evaluation boards, and for applications with an operating temperature range from -65°C to +165°C.
Developers looking to use these connectors in telecommunications, broadband, and antenna-related wireless applications or testing equipment can obtain free samples from Würth Elektronik.
