Narda-MITEQ DC blocks are engineered to prevent unwanted direct current (DC) and low-frequency signals from passing through RF and microwave transmission paths while allowing desired RF signals to pass with minimal insertion loss. Designed to isolate DC bias voltages, reduce unwanted signal leakage, and protect sensitive components, our coaxial DC blocks support reliable signal integrity and system performance across broadband frequency ranges from 10 MHz to 18 GHz, depending on model.
These solutions are ideal for integration into amplifier circuits, satellite communications (SATCOM) transmitters and receivers, high-speed optical communications systems, and RF test and measurement equipment. With compact, lightweight designs and multiple connector configurations, Narda-MITEQ DC blocks support demanding defense, aerospace, communications, laboratory, and commercial environments where dependable signal isolation is essential.
