- SSMA Product Series
FEATURES & APPLICATIONS
SSMA series are 50 ohms screw coupling subminiature coaxial connectors. With the characteristics of small size, light weight, wide frequency range and high reliability, they are widely used in applications where size and weight are critical, such as high accuracy miniaturized mobile electrical instruments, network, and connected to RF cables to transmit RF signals. In assembly of high accuracy semi-flexible cable, SSMA can work up to 18GHn or higher.
