MMCX connector, which stands for Metric Miniature Connector, is a type of coaxial connector that can be used in radio frequency communications. It is mainly designed for use in mobile phones, handheld devices, and other systems that require a lightweight and reliable connection. The MMCX connector is a small form factor connector that has an approximate size of 3.5mm, allowing it to easily fit into even the most cramped spaces. It is commonly used in telecommunication and radio frequency applications, due to its robustness and high-frequency performance.

The MMCX connector is available in several distinct series, including the J, P, H, ST, and TH1 Series. Each series offers a unique configuration, designed to suit the specific application requirements. As an example, the J Series includes a crimpable-only interface, used for low frequency requirements, while the P and H Series offer soldered interfaces for higher frequency applications. The adapter-style ST and TH1 Series provide a great deal of flexibility, due to their ability to be converted from male to female and vice versa, allowing for easier connection in mixed-gender installations.

The application fields for the different series of the MMCX connectors vary from low frequency to high frequency applications. For low frequency requirements, the J Series provides an effective connection for systems that are operating at frequencies up to 500 MHz. The P and H Series are ideal for higher frequency requirements, up to 5 GHz or higher. The adapter-style ST and TH1 Series are designed to provide a high-performance solution for systems operating in frequencies up to 4 GHz.

The working principle of the MMCX connector is based on impedance matching, which means that both the inner and the outer conductors of the coaxial cable have to be matched in order to maintain consistent signal characteristics. The impedance matching is achieved by adjusting the end-to-end spacing between the inner and the outer conductors, as well as the overall length of the cable. The adjustment of the spacing and the length of the cable is often achieved by using an adapter or a special connector.

The MMCX connector is a reliable and robust connection for a wide range of RF applications, due to its light weight, small size, and high-frequency performance. It is available in various series, each providing a unique configuration to meet the application requirements. The working principle of the MMCX connector is based on impedance matching, which ensures optimal signal characteristics.
