The SMB series RF coaxial connector is a small push-in RF connector, and its impedance can be divided into 50Ω and 75Ω. The 50Ω series can reach 4GHz, and the 75Ω series can reach 2GHz.
SMB series RF coaxial connectors have the characteristics of small size, convenient insertion and removal, excellent electrical performance, light weight, etc., and meet the standard MIL-C-39012.
SMB series RF coaxial connectors are suitable for applications such as high-frequency loop connection of wireless communication equipment and electronic instruments, among which the cable connector type is the most used.
