DC Blocks, Bias Tees, and Detector Mounts

Microlab DC Blocks are used to prevent the flow of direct current and low frequency current surges along the inner and/or the outer conductors of a transmission line, while permitting the unimpeded flow of RF signals. Applications include the blocking of current surges that can occur in subway tunnels and rail systems, at base-station/cell-sites during lightening storms, to route DC to tower mounted amplifiers (TMA’s) or whenever DC isolation is required. Units are available with a DC block on the inner and/or outer conductor, and all units are built with special attention to effects of PIM.
