This DC Block 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. The unit consists of a length of 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.
FEATURES / BENEFITS
• Broadband frequency range from 80 to 3800MHz • 3 kV High voltage rating
• Inner and Outer conductor separated
• PIM optimized design to minimize network interferences
• Minimal RF insertion loss • 7-16 male/female connector
