As an important electrical connection component, RF coaxial connector plays an important role in various electronic equipment, instruments and electronic information systems. After decades of development, RF coaxial connectors form an independent and complete professional system, which has become an important part of the connector family. The rapid development of the domestic information industry has effectively spurred the growth of the RF connector market. In order to introduce readers to the latest market and technical information in the field of RF coaxial connectors, this article interviewed Gao Qian, deputy general manager of Xi'an Kenet Technology Co., Ltd., and Zhou Fubing, deputy general manager of Sichuan Huafeng Enterprise Group Co., Ltd. and Amphenol China. District Marketing Manager Xiao Yi, I hope their views can help readers understand, choose and use RF coaxial connectors. Versatility and reliability are the development trend of RF coaxial connectors In addition to the pursuit of two key technical projects, miniaturization and high frequency, RF coaxial connector manufacturers continue to improve the versatility and reliability of their products. In addition to the signal connection function, the RF connector now also has the functions of processing signals, such as filtering, phase adjustment, mixing, attenuation, detection, and limiting. In addition, low standing wave, low loss, large capacity, high power and ease of installation have also become the goal of manufacturers. “With the change of production process, the technology of stamping has appeared. It used to be turned. Now it is formed by stamping once, so that the volume can be made smaller and the height of the whole connector is less than 2 or 3 mm. Now some coaxial connectors have been made as small as sesame.” Xiao Yi, Marketing Manager of Amphenol China, described the technical status of RF coaxial connectors. In terms of RF coaxial connector production technology, domestic manufacturers and international manufacturers are comparable, regardless of the level of research and development, production technology and marketing, attracting attention from foreign counterparts. Xi'an Kenet Technology Co., Ltd. is a professional manufacturer of RF coaxial connectors. When it comes to the technical development trend of RF coaxial connectors, Gao Qian, deputy general manager of the company, said that in order to meet the miniaturization and modularization of communication equipment. And the need for integrated development, the demand for smaller, densely packed, blind-mountable, surface mount RF coaxial connectors will increase significantly. He said: "With the development of wireless technology, there will be more new consumer end products that use wireless technology. The demand for some RF connectors with cheaper composite materials and structures will increase significantly. With the development of satellite communication and military industry, the demand for RF coaxial connectors with higher application frequency and higher reliability requirements will increase."HSPACE=12 ALT="肖一: Through the stamping technology, there are now coaxial connectors It has been made as small as sesame. "> The company will produce more compact, close-packed RF coaxial connectors in the future, such as MMCX series, GPO (SMP) series, D-Sub series, 2 Mm series, etc. At the same time, the company has put a lot of effort into improving product installation efficiency and reliability. For example, they have restructured the C4 structure on the basis of the international C4 series, and introduced the TC4 series, which effectively improved the insertion rate. In another example, the flexible blind-plug RF coaxial connector (DB4 series) has a constant impedance throughout the insertion process and maintains good electrical performance, so that the frequency of use of the D-type blind-plug connector is increased from 0-2 GHz to 0-32GHz. Sichuan Huafeng Enterprise Group Co., Ltd. is a domestic large-scale connector manufacturer that has been restructured by a military enterprise. The company has also spared no effort to develop product technology to enhance its international competitiveness. The company will invest resources in the development and series expansion of high-tech RF connectors in the near future. The main direction is the SMT and press-in RF connectors with certain technology foundations to enable the company to be highly skilled and value-added. There is a breakthrough in the product. Zhou Fubing, deputy general manager of the company, pointed out that RF connectors have been developed in the direction of surface mount SMT and press-in solderless installation of Press-in. This trend will be further strengthened in the next year or two and will eventually become the mainstream of RF connectors. . Xiao Yi also said that the RF coaxial connector is a very traditional product, like all connectors, it will be miniaturized. And performance will get better and better. Its development trend is as high density, miniaturization and high speed as other connectors. Many of the company's new products are custom-made products, with annual sales of new products accounting for 30% of total sales. Prices continue to fall, manufacturers reduce costs As competition intensifies, the market price of RF coaxial connectors continues to fall, and various suppliers are looking for ways to reduce costs, such as expanding production scale to resolve cost pressures and realizing operating costs through localization and localization. Reduce and so on. Through nearly two years of field and equipment upgrades and expansions, Knite has reached an annual output of 10 million RF coaxial connectors and 6 million RF cable assemblies. Gao Qian said: “After the expansion of production capacity, our delivery time has increased by 20% to 30% compared with the previous period. The price has also decreased. The price of conventional products has decreased by about 3-5% compared with last year, and the price of new products has decreased compared with last year. About 10-15%." Huafeng's Zhou Fubing said: "Our RF coaxial connectors are usually delivered in about 3 weeks, and can be done for 10 days for key customers. From the situation in recent years, The price of the RF coaxial connector can be said to be a straight down, and its profit is quite low." The company's plan will be improved in many ways to achieve leapfrog development, in the next three years, the sales target is 50 million US dollars. The number of newly owned patents is no less than 100; the quality control objectives of 6σ are realized in communication products; the core products are adjusted to connectors in IT, automotive, military and special fields, and more extensive international cooperation. Xiao Yi said that Amphenol is directly delivered to the customer, so it can fully meet the customer's delivery. He said: "The price trend of the entire connector industry is stable and declining. We will strive to continuously reduce costs, including the localization of employees, the improvement of production efficiency and the integration of all resources of the company to achieve rational use and localization of raw materials procurement. In the next three to four years, the factory will be expanded in China at a rate of more than one per year.” To the buyer: focus on the comprehensive cost for the customer in selecting the supplier's standard, three industry professionals have given themselves the opinion of. Gao Qian said: "First of all, of course, the original manufacturer of the product should be selected as much as possible to reduce the extra cost incurred in the middle of the distribution process. At the same time, the technical and quality aspects can be more directly supported and guaranteed by the manufacturer; secondly, the customer must have their own products. The use requirements are relatively clear, avoiding the high cost caused by the pursuit of unnecessary high performance, high quality and high reliability products, and avoiding the low cost of excessive pursuit of cost, the quality and performance of the products cannot meet the requirements of use. "" A remarkable feature of RF connectors is that scale produces benefits. Therefore, customers should choose mainstream products or products that represent the future development direction when selecting models. Manufacturers are likely to carry out large-scale operations and improve cost performance. Customers get benefits." Zhou Fubing said. Xiao Yi's words are a good summary of how customers choose suppliers: "Customers can't only compare the price of products when choosing suppliers. Customers must have some dependence on after-sales service, and suppliers to suppliers. Say, service is also a part of the cost, it is an additional thing; another added value is the previous investment, our design center cooperates with customers to do design-in, teach them how to use our products, these are the initial investment. Customers should Take into account these factors to determine if a supplier can really meet your needs."
