Coaxial Connectors (RF)

Coaxial connectors, commonly referred to as RF connectors are specialized connectors typically used for radio frequency (RF) and microwave signal applications in the electronics industry. One type of coaxial connector which is specifically designed to provide excellent electrical performance and reliability in signal transmission applications is the BJ154AC-201. This article looks at the BJ154AC-201 application fields and working principle.The BJ154AC-201 is an axi-symmetrical coaxial connector designed for coaxial cable applications. It features a high-performance impedance and low electromagnetic radiation that make it suitable for use in high-speed, high-density digital applications. This connector is available with contacts plated in gold, nickel, and silver and includes an anodised aluminium shell, PTFE (V0) insulation, and connectors made of brass. It also comes with a COTS or customer-specified rubber gasket for optimal signal transmission. It is a type of coaxial connector that is especially well-suited for satellite systems, shortwave antenna, digital and analog radio systems, as well as broadcast TV transmission equipment.In practical applications, when the BJ154AC-201 is used to couple two circuits, a ground plane is typically constructed on the PCB which connects the enclosure to the ground. This provides the protection against unwanted frequencies that can reduce the signal transmission quality. After the ground plane is made, it is essential to connect the VG-4-001 adapter to the BJ154AC-201 and then to the ground plane. This ensures proper signal transmission between the two circuits.The BJ154AC-201 relies on an axial transverse field configuration to achieve its high performance in signal transmission. The connector features an inner conductor which is surrounded by a concentric layer of dielectric material and a metallic outer conductor. This design provides a low-impedance signal path and ensures minimal signal loss during transmission. It also minimizes the effect of adjacent cables, enhances signal shielding, and reduces the overall Price/Performance ratio.The BJ154AC-201’s performance is further enhanced by its superior electrical connectivity. This coaxial connector has three contact points which, when combined with a suitable adapter, provide a reliable and uninterrupted transmission of signals. The first contact point is the inner contact which is a ‘soldier’ type and provides signal transmission between the two circuits. The second point is the metallic outer contact which provides impedance matching and acts as a shield for the inner contact. Finally, the third point is the grounding point which completes the electrical circuit and reduces the effect of any external interference.In conclusion, the BJ154AC-201 is an axi-symmetrical coaxial connector that is designed to provide superior electrical performance and reliability. It relies on an axial transverse field configuration and three contact points to ensure a low-impedance signal path and a secure transmission of signals. This connector is ideal for applications such as satellite systems, shortwave antenna, digital and analog radio systems, broadcast TV transmission equipment, and other high-speed, high-density digital applications.
