Coaxial connectors, or RF connectors, as they are commonly referred to, are an essential part of any wired or wireless communications system. They are designed to interface with the antenna system and provide a secure and reliable connection. Coaxial connectors come in various shapes and sizes, and each type can be used for a specific application. Model 142-0711-871 coaxial connectors are commonly used for radio frequency (RF) applications, and their design and working principle are described in this article.

Model 142-0711-871 coaxial connectors feature a standard precision SMA interface size and an impedance of 50Ω. The connector shells are manufactured from stainless steel and feature a unique two-piece design that minimises component fatigue and provides environmental protection. The socket is designed with a hexagonal shape, making it easy to insert and remove the cable, while the metal shell provides additional shielding and rigidity to the assembly. The contact pin is gold plated for superior conductivity and longevity.

In terms of their working principle, model 142-0711-871 coaxial connectors are designed to minimise return loss when connecting two antenna systems. This is achieved through a combination of electrical characteristics such as the connector’s impedance, frequency rating and VSWR (Voltage Standing Wave Ratio). The connector’s impedance is matched to the antenna system through the selection of the appropriate cable, and this also helps to reduce reflections and noise generated by the antenna. The frequency rating of the connector is determined by the cable and determines the range of signals that can be transmitted. The VSWR is a measure of the power reflected back from the cable and is given a numerical value. VSWR values of 1:1 indicate that no power is being reflected back and are ideal for avoiding interference.

The application field of model 142-0711-871 coaxial connectors mainly covers low and medium-powered RF applications where data rate and performance are not critical factors. It is suitable for fixed and mobile wireless communication systems such as WLAN, WiMAX and 3G/4G mobile networks. It is also a good choice for digital and satellite broadcast receivers, antenna systems and GPS systems. It is also used in optical communication systems, medical equipment, audio/video systems and high-speed data transmission.

In summary, model 142-0711-871 coaxial connectors are a reliable and cost effective solution for connecting antenna systems in radio frequency applications. The connectors are designed to ensure a secure and reliable signal transmission, while minimising return loss for maximum performance. Their two-piece design provides additional protection and rigidity to the assembly, and their versatile application range makes them suitable for various RF communication devices.
