The 4.3-10 connector was proposed by Ericsson and Kathrein and jointly designed by Huber+Suhner, Rosenberger, Spinner, and Telegartner. The 4.3-10 connector is smaller in size, lighter in weight and excellent in electrical performance. The model 4.3-10 connector is designed to meet its design objectives (to more fully meet modern application requirements and improve reliability through its low PIM under various torque conditions). The 4.3-10 coaxial connector adopts radial contact, i.e. separation between its electrical and mechanical mating surfaces. This design enables the connector to achieve the desired transmission and passive intermodulation PIM performance even if it is not fully screwed. Due to the high performance, high reliability and high package density characteristics of the 4.3-10 connector, the 4.3-10 connector is the preferred choice for current 4G-LTE, 5G, DAS and other applications and system modifications.
