DC Block, SMA Male to SMA Female, 18 GHz (Inner Type) [RFS-530002] High-Frequency Precision Galvanic Isolation Component This precision 50-Ohm Inner DC Block features sub-miniature SMA Male to SMA Female connectors, offering low-reflection RF transmission up to 18 GHz. By isolating the center conductor while keeping the outer shield ground continuous, it blocks DC voltages and power surges from reaching delicate spectrum analyzers, receivers, or active LNAs. Built with a passivated stainless steel or gold-plated brass body and a solid PTFE dielectric, it is optimized for high-frequency lab testing and ground loop elimination.
