Description
The HDC18NIO in an N Type RF DC Block Inner and Outer with operating frequency of 10 MHz to 18 GHz at a maximum voltage of 200V.
An RF DC Block is a device used prevent the flow of direct current through a transmission line and introduce minimal RF noise. There are three type of DC blocks: Inner, Outer, and Inner/Outer. Inner DC Blocks have a capacitor in series with the center conductor, outer has a capacitor in the outer conductor and lastly Inner / Outer DC blocks have both. HASCO has various DC Blocks with various connectors and frequency configurations.
