Flange RF Adapter N-Female to SMA-Female (25×25 mm Panel Mount)
The N-Female to SMA-Female flange RF adapter is engineered to ensure reliable and stable high-frequency connections in professional telecommunications and RF equipment. Featuring a robust 25×25 mm square flange mount, it’s perfectly suited for secure installation on device enclosures, antennas, panels, and base station frames, where mechanical strength and low signal loss are critical.
This adapter combines a N-type female connector on the signal input side with a SMA female connector on the output side, offering broad compatibility with popular coaxial cables such as RG402 (semi-rigid), RG316, and LMR-100. Its precision-machined body and quality materials deliver consistent performance across a wide frequency range up to 6 GHz.
The body is made of nickel-plated brass, ensuring corrosion resistance and mechanical durability. The gold-plated center contact enhances conductivity and minimizes loss, while the PTFE (Teflon) dielectric offers excellent thermal and electrical insulation for high-frequency signals.
