DC Block, N Male to N Female, 18 GHz (Inner Type) [RFS-530004]
High-Frequency Precision Galvanic Isolation Component
Designed to protect sensitive microwave test instruments from DC bias and low-frequency transients, this 50-Ohm Inner DC Block operates up to 18 GHz. It features a threaded Type N Male to Type N Female interface, utilizing an embedded galvanic isolation capacitor on the center conductor while maintaining a continuous outer shield. Constructed with a passivated stainless steel or tri-metal plated brass body, this high-performance block ensures minimal insertion loss and low VSWR up to 18 GHz.
