Introduction
The FME connector is a tiny RF coaxial connector that is commonly used in mobile communication, GPS, cellular, and IoT applications. FME connections, known for their tiny size, lightweight construction, and dependable RF performance, are especially popular in automotive and space-constrained installations where traditional RF connectors such as SMA or N-Type may be too cumbersome.
FME stands for For Mobile Equipment, which emphasizes its initial design purpose for mobile radio systems. FME connectors are now widely used in GSM, LTE, GPS antennas, telematics devices, and vehicle-mounted communication systems.
What is an FME Connector?
An FME connector is a threaded RF coaxial connector that can normally handle frequencies up to 2 GHz. Its thin design allows it to readily fit through small spaces in vehicle panels and device enclosures, making it suitable for antenna installation.
Types of FME Connectors :
1. FME Male Connector
- Features an internal pin.
- Most frequently utilized in RF cable assembly.
- Perfect for antenna and device-side hookups.
2. FME Female Connector
- Has a receptacle contact.
- Frequently used on antennas and extension cables.
3. FME to SMA Adapters
- Converts FME into SMA Male or Female
- Used to link mobile antennas to RF modules.
4. FME to SMB, MCX, or MMCX Adapters
- Common in GPS, GSM, and embedded wireless devices.
- Helps interface tiny RF boards with external antennas.
5. Right-Angle and Straight FME Connectors
- Straight is for direct inline connections.
- Right angle: for tight installation spaces.
