The A-CRF-NMNM-LL4-300 is an RF cable from manufacturer Moxa, designed for use in industrial high-frequency applications. It connects two N connectors (male to male) and has a fixed length of 3 metres. The cable is based on the LMR-400 Lite cable type, designed for low-loss and reliable signal transmission at high frequencies. Due to its electrical and mechanical properties, it is particularly suitable for industrial wireless applications, antenna installations, and test environments where stable high-frequency transmission is required.

Applications
The cable is designed for use in environments subject to high mechanical stress and extreme temperatures. It is commonly used in industrial communication technology, for example, to connect radio modules, antennas, or test equipment. The specific frequency range of 5150 to 5875 MHz makes it especially suitable for applications in the 5.8-GHz band, such as in WLAN systems or industrial radio networks. Its robust construction also allows use outdoors or in harsh production environments.

Functions and Equipment in Detail
The cable features an impedance of 50 Ohm, which is the standard impedance for many high-frequency systems and ensures optimal signal transmission without reflections. The insertion loss is maximally -1.6 dB, indicating low signal loss and ensuring high signal quality. The VSWR value (Voltage Standing Wave Ratio) is maximally 1.65:1 in the frequency range of 5150 to 5875 MHz, indicating low reflection and thus efficient power utilisation. These values are critical for signal integrity in high-frequency systems.

Technology Explained Simply
The designation LMR-400 Lite refers to a specific coaxial cable type that offers a good balance between flexibility, mechanical strength, and electrical properties. The cable has an outer diameter of 10.29 mm and a minimum bending radius of 24.5 mm, making it flexible enough to be routed in confined spaces without impairing its electrical characteristics. The use of N connectors (male to male) ensures a secure and mechanically stable connection designed for industrial use.

Compatibility and Accessories
The cable is compatible with devices using N connectors (male) and operating in the frequency range of 5150 to 5875 MHz. It can be used in combination with antennas, radio modules, or test equipment that support this interface. Its use in industrial networks, particularly in automation technology, is typical.

Installation and Mounting
Installation is performed by simply connecting the two N connectors to the respective devices. Due to the minimum bending radius of 24.5 mm, careful bending of the cable is required to avoid mechanical damage. The robust construction allows mounting in harsh environments, with a temperature resistance of -40 to 85 °C enabling a wide range of applications.

Operational Advantages
The cable offers high mechanical durability and reliable high-frequency transmission. The low insertion loss and low VSWR value ensure stable signal transmission, which is particularly important in critical industrial applications. The wide operating temperature range allows use in extreme environments without impairing electrical properties. The use of N connectors ensures universal connectivity with many devices in the high-frequency range.
