415-0037-048 is a fixed-length cable assembly designed to connect SMA straight plug connectors to BNC straight plug connectors using RG-58 coaxial cable at a length of 48 inches. The assembly features a 50-ohm connector impedance with a maximum operating frequency of 4 GHz (limited by the BNC connector), providing reliable signal transmission for RF and microwave applications. The RG-58 cable offers a dielectric withstanding voltage of 1000 Vrms and a working voltage of 335 Vrms, ensuring robust performance in demanding environments. This cable assembly is commonly used in test equipment, instrumentation, data acquisition systems, and RF signal distribution applications where standardized interconnections between SMA and BNC connectors are required.
