RF connector selection
1 . The selected RF frequency range of the connector to meet the practical use.
2 . Typically, the electrical performance of the RF connector straight better than angled, may be selected based on actual usage.
3 . The selected RF connector to have a small standing wave ratio.
4 . The selected RF connector to have a small insertion loss.
5 . The selected RF impedance match with the RF connector to the connector or the mating cable.
6 . Threaded RF connector EMC than any bayonet, push-pull RF connector is better.
7 . When an IM requirements, and coating materials to consider the RF connector.
8 . When RF connector meets the general requirements, do not use high-performance RF connector.
The RF coaxial connector must correspond to the wire on the crimping terminal of the electric heater to avoid short circuit accidents. Ceramic materials and similar materials that are not tightly sintered cannot be used for additional insulation or reinforced insulation. The main reason is that similar materials often have cavities or bubbles in the material during the firing process. If it is placed in a humid use or storage environment, the performance of the material will be affected. If similar materials are to be used as additional or reinforced insulation, they must pass the red medicine immersion test to analyze whether they are tightly sintered. Rather than because of the brittleness of this material, whether brittle or not is a subjective judgment. Generally, if it can pass the impact test, we can probably think that it meets the requirements of mechanical strength.
The future development prospects of my country's connector market are very good, and with the continuous migration of electronic manufacturing service providers from all over the world to China, China is gradually becoming the world's connector manufacturing center, and the production and sales of connectors will continue to be steady. increase. Although the connector is not the core of various products, it is indeed an indispensable supporting role. Without connectors, all kinds of devices cannot be effectively connected, and even less can be formed as a whole to perform its functions. In the foreseeable future, the market demand for connectors will continue to grow, and at the same time, the technical requirements for connectors in related industries will become higher and higher.
The importance of coaxial connectors in electronic systems is often underestimated. Using cheap connectors often end up paying high costs. Choosing the wrong connector will cause a lot of trouble, such as system failure to operate normally, rework and repair, and loss of customers. This shows how important it is to choose a suitable connector for an electronic system. In fact, not only the connectors in the electronic system cannot be underestimated, but all the devices used in the connectors cannot be ignored. The service life of the connector has become a measure of its reliability, so increasing the service life of the connector has also become a design guide.
The metal components in a good RF coaxial connector should be able to maintain the physical state without changing within a certain temperature, so as to ensure its high performance. It is usually stipulated that it should be able to withstand a maximum of 200 degrees and a minimum of minus 65 degrees. The influence of humidity on the RF coaxial connector is the influence of water. Because water is corrosive to metal components, it also has a certain degree of conductivity and can reduce insulation, so the component material of the connector must be selected with the least impact of water. The RF coaxial connector should be able to work normally for at least 96 hours at a relative humidity of 90%-95% and a temperature of about 40 degrees. Salt spray means that the water contains salt, which can chemically corrode metal components and affect the electrical performance of the RF coaxial connector.
The RF connector is generally considered to be a component that is attached to a cable or installed on an instrument as a component for electrical connection or separation of transmission lines. The RF connector is a mechatronic product, which mainly serves as a bridge.
