DC-Blocks for RF and mmWave Systems up to 110 GHz
DC-Blocks are essential passive components in RF and mmWave systems, enabling DC voltage separation while allowing high-frequency signals to pass through coaxial transmission lines without impediment. These components utilize internal capacitive coupling to block direct current while maintaining minimal insertion loss and excellent VSWR performance across their operational bandwidth.
