The HR-26E from Microlab is an Inner DC Block that operates from 250 to 5925 MHz. The block consists of a length of coaxial line with a series capacitor in the center conductor to block the flow of DC and low frequencies, while passing RF with negligible loss or reflections. It provides an insertion loss of less than 0.10 dB and return loss of up to 20 dB.
This connectorized DC Block has 4.3 - 10 M/F connectors with a breakdown voltage of 3 kV and can handle up to 500 W of average power. This IP65-rated and RoHS compliant module is ideal for blocking current surges in subway tunnels and antenna sites during lightning storms. It is ideal for use in LTE-LAA deployments with multiband antennas.
