HR-28D DC Blocks

2022-09-14
●Microlab HR-28D is used to prevent the flow of direct current and low-frequency current surges along the inner and outer conductors of a transmission line while permitting the unimpeded flow of RF signals. Applications include the blocking of current surges in subway tunnels and at antenna sites during lightning storms.
●The unit consists of a coaxial line with a series capacitor in both the center conductor and outer conductor to block the flow of low frequencies while passing RF with negligible loss or reflections.
●Multi-Band Frequency Range
●250 Watt Average Power Rating
●3 kV DC High Voltage Rating
●Minimal RF Insertion Loss
●Guaranteed Low PIM
●RoHS compliant
●High Reliability
●7/16 DIN connectors
