Coaxial Connectors (RF)

MS-156NB Application Field and Working Principle

A coaxial connector is a type of RF connector designed for transmitting radio frequency signals. The MS-156NB is a specific type of coaxial connector frequently used in electrical engineering applications. It is a compact coaxial cable assembly designed to transfer and receive high-frequency signals, complying to the Type N MIL-STD-348 standard.Applications of the MS-156NB connector include communications systems, RF amplifiers, cellular networks, military hardware, and wireless devices. It is also widely used in robotics, laboratory experiments, and medical electronics.The MS-156NB connector is composed of a male part, which contains a center pin, and a female part with an outer sleeve and a center pin receptacle. The center pin is designed to provide connections with adjacent components on the circuit board in order to form the coaxial connection. The center pin’s length is typically tailored to the desired transmission range. Meanwhile, the female part includes a rubber seal, which functions as an environmental and EMI protection, preventing the connector’s inner elements from being exposed to moisture or dust.The working principle of the MS-156NB connector lies in the elimination of interference occurring between the transmission lines and its related components. This is accomplished by controlling the RF signal’s return flow and attenuating the undesired waves travelling in the circuit. As a result, the signal quality is significantly increased.Moreover, the MS-156NB’s integrated design with its grounding and EMI protection helps to achieve lower voltages for transmitting between closely located components and avoids shorts. Consequently, these connectors are useful in applications where electromagnetic radiation is being transmitted or received by antenna, providing improved signal fidelity. The MS-156NB connector is often used where impedance matching is required. Impedance matching is a critical factor in the design of the coaxial cable assembly as it helps to minimize reflection and ensure the transmitted signal reaches its destination, without significant distortion or loss of power. This is achieved by configuring the transmission line to match the impedance of the connectors to the impedance of the combined load.Overall, the MS-156NB connector is a widely-used coaxial cable assembly, ideal for applications requiring a lower power connection with high-fidelity signals. The high-performance connector offers excellent environmental protection, along with the EMI filtering and impedance matching necessary for successful transmission in many complex systems.
