The LMR300 SMA Male to N Male coaxial cable is designed to meet the requirements of modern RF and microwave systems that demand low signal loss and high durability. The cable features a 50-ohm impedance, ensuring compatibility with a wide range of RF equipment. Its LMR300 construction includes a solid center conductor, gas-injected foam dielectric, bonded aluminum foil, and a tinned copper braid, providing superior shielding effectiveness and minimal signal leakage.

Connector interfaces include an SMA male connector, known for precision and compact design, and an N male connector, valued for its ruggedness and excellent performance at higher power levels. Both connectors are manufactured with high-quality materials such as brass with nickel plating or gold-plated contacts to ensure corrosion resistance and long service life.

The cable supports frequencies up to several GHz, making it suitable for applications including antennas, routers, amplifiers, and RF testing devices. It maintains low attenuation over longer distances compared to standard coaxial cables of similar size. Additionally, the flexible yet sturdy outer jacket allows for easy installation in tight spaces while maintaining mechanical strength.

Custom lengths and configurations are available to meet specific project requirements, ensuring optimal system integration and performance.
