High-frequency signal transmission in industrial telecommunications applications between machines, for connecting measuring instruments and antennas - here the slender yet robust SMA connectors are used. Würth Elektronik eiSos offers a comprehensive range of SMA products, ranging from connectors and adapters to pre-assembled connection cables. A constant impedance of 50 Ω is crucial to ensure the best transmission efficiency. This requires meticulous construction of the plugs. For example, Würth Elektronik eiSos does not offer angular connectors with internal solder joints, but rather with a continuous single contact that minimizes signal losses at the bend. The compensating air volume and PTFE material in the design of the connector interior are accurately calculated to achieve consistent impedance matching. Low impedance deviations for higher frequencies Standards and protocols like 3G, 4G, LTE, WLAN and Bluetooth dominate applications in consumer electronics, industry and telecommunications. In view of this wide range of applications, SMA series are normally optimized for frequencies below 6 GHz. Würth Elektronik's SMA connectors, however, operate in frequency ranges up to 18 GHz. So users from a wide variety of fields have more HF technologies at their disposal. Besides this, impedance matching can also be achieved with different requirements or signal line layouts - but it is important to use suitable connectors in the right way. For example, with end-launch connectors available for a wide range of PCB thicknesses, the signal line design on the PCB must distinguish between a socket with a round post contact and a flat tab connection. Würth Elektronik eiSos would be pleased to advise on such questions and also offer unorthodox solutions, such as THR components suitable for reflow soldering. As the ultimate goal is signal quality, Würth Elektronik eiSos takes the material and processing of its HF coaxial connectors extremely seriously. All connector designs meet the MIL-PRF-39012F standard and come with MIL-STD-348 compliant connector interfaces. www.we-online.com/coax
