In the 5G era, how to choose RF connectors?

RF connector,Usually considered to be a component mounted on a cable or instrument 。along withPromotion of 5G commercial use，G equipment faces upgrading，RF connectorastransmission lineon the roadElectrically connected or separated components, traditional RF connectors can no longer meet the requirements in terms of transmission rate and reliability.5G massive MIMO antenna usage requirements.

The design of MIMO antennas focuses on high-speed signal transmission between a large number of antenna arrays and radio frequency transceivers between PCB boards. Therefore, the development of high transmission rate, high power, and small size radio frequency connectors is urgent. Simply put, we need "smaller, lighter" high-end connectors.

For example, widely used in distributed base station systemsIn order for RRH (remote radio head) to be easily, conveniently and reliably installed on tower tops and in dense urban environments, its design must be very compact and its size must be controlled as much as possible. This requires that the coaxial interconnection system that carries its radio frequency signal transmission must also be simpler and more compact. Traditional and complicated cable assembly connections are being replaced by "board-to-board" coaxial connector connections that are simple, compact, reliable, and can carry more than 100W of RF signal power.In order to meet such requirements, Golden Navigationkinghelm company develops and produces related products.

golden navigation markkinghelmRF coaxial connectors can be used to build base stations, expand network coverage and increase traffic.U.FL antenna base,kinghelm系列的U.FL antennas can be mated to a variety of miniature devices meeting a wide range of frequency requirements, and the connectors provide high frequency performance from DC to 6GHz with a V.S.W.R. maximum of 1.3 to 1.5. This will be of great help in promoting the 5G process.

golden navigation markkinghelmThe connector is an ultra-small surface mount coaxial connector withThe standard fit height is 1.9mm or 2.3mm, or 2.4mm, and the maximum is 2.0 or 2.4mm, 2.5mm. Secondly, the installation area of ​​the U.FL antenna base is small. If it is placed on the board, it occupies an area of ​​7.7 square millimeters and is light in weight, only 15.7mg. Furthermore, it supports high-frequency transmission up to 6GHz and automates the board layout. The U.FL antenna base is terminated with ultra-tinned coaxial (fluorinated resin insulated) cable. Standard diameter 0.81mm ultra-fine coaxial cable (single braid shield) is used for plug termination, ensuring a safe and stable connection. Coaxial cables are available for different OD needs. Available extraction tools are used during installation to ensure correct disconnection of plugs and sockets. A tactile click sensation confirms full mating condition, ensuring complete electrical and mechanical connections. Finally, U.FL RF coaxial connectors meet halogen-free environmental requirements, with a maximum Br-900 ppm, a maximum Cl-900 ppm, and a maximum combined Cl + Br of 1,500 ppm as defined by IEC61249-2-21.
