Difference between SMA connector and SMB connector?

SMA series RF coaxial connector is a small RF coaxial connector with threaded connection. Its characteristic impedance is 50 ohm busbar and the frequency range is 0-18ghz. it has the advantages of superior mechanical and electrical performance and high reliability. It is widely used in telecommunication, networking, wireless communication, testing and measuring instruments, microwave communication, aerospace and navigation, weapon system,, microwave measuring equipment and other fields. At present, most of the structures of SMA RF connectors and their coaxial microstrip connectors are designed based on earlier structures. Take the extended medium shape memory alloy coaxial microstrip connector as an example, in the early structure, the method of fixing the inner conductor and insulating medium is to punch holes in the metal shell and insulating bracket and inject epoxy resin, i.e., the method of epoxy pins; the shielding box and the connection with the microstrip line uses the insulating medium and the inner conductor lengthening, the connector's inner conductor and the microstrip line welded, i.e., the lengthening of the medium type; of course, the lengthening part not only has to satisfy the Impedance requirements, but also to meet the microstrip line connection with the microstrip line better shape size requirements; connector flange connectors, switches (two-hole or four-hole) and shielding box is directly fixed with screws, do not take other measures.SMB connector is a small push-in RF coaxial connector according to the standard Mil-C-39012 development and production. It has two kinds of characteristic impedance: 50 ohm and 75 ohm, and the frequency range is 0-4 GHz. it has the characteristics of small size, light weight, easy to use, fast plugging and unplugging, and superior electrical performance, etc. Differences between the SMA connector and the SMB connector: different impedance connectors have different impedance, usually only 75 ohm and 50 ohm; there are some differences in appearance, but the internal distortion remains the same; The caliber interface is different and the connection is different. The same model can be used with each other, different models need adapters to use each other.-2、About Evergrande Electronic Products Network platform related to the introduction and sales of products briefly: Evergrande Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand what connectors | harness | wire and cable products we can provide solutions, please contact the following Division I business personnel; If you have related [connectors | wire harness | wire and cable products] sales / resources and promotion needs, please click on the "¡¡ Business Cooperation ←" with the person to discuss!
