SMA is designed for use from DC to 18 GHz, but is most commonly used for hand-held radio and mobile telephone antennas, and more recently with WiFi antenna systems and USB software-defined radio dongles. It is also commonly used in radio astronomy, particularly at higher frequencies (5GHz+).
FAKRA* connectors have been especially designed to fulfill the tough requirements of the automotive industry. A sophisticated coding system of the standard plastic housing offers 13 mechanical and colored codings and one neutral coding.
It has a frequency bandwidth, excellent performance, high reliability, long life characteristics
application for Antennas, Wireless LAN Devices , Coaxial cable, Wi-Fi Radios External Antenna and so on
Coaxial cable differs from other shielded cables because the dimensions of the cable are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a transmission line.
