FME connectors have a compact and lightweight design, typically with an outer diameter of approximately 9.5 millimeters, making them ideal for applications that have strict limitations on weight and space. There are two common interface forms for FME connectors - threaded locking type and push in quick connect type. The frequency range supported by FME connectors is generally from DC to 2GHz, and some high-performance models can be extended to 3GHz or higher. The standard FME connector provides a characteristic impedance of 50 ohms, and some good FME connectors have low insertion loss, which means that there is less energy loss during signal transmission. Meanwhile, the return loss will also be kept at a low level to reduce the impact of reflected waves on signal quality.
