Unwanted DC abated

. Published on

Hughes latest DC Blocking connectors prevent the flow of direct current (DC) and low frequency current surges up to 3000V along the inner and outer conductor of transmission lines while permitting unrestricted flow of RF signals.

High performance DC Blocking with Unrestricted RF Signal Flow

Hughes DC Blocks are manufactured with great precision from premium grade materials to create a best in class connection device with insertion loss of < 0.1 dB with highly effective DC blocking capability. High quality, Teflon based dielectrics cause high voltage breakdown with high temperature capability that is stable over wide temperature ranges and effectively isolate inner conductors up to 3000V DC.

Multiple Interface and Form Options

Hughes DC Blocks come in three forms to ensure optimal performance in any situation;

  1. Inner DC Blocks feature blocking capacitor plates in series with the inner conductor,
  2. Outer DC Blocks feature the capacitor plates in series with the outer conductor
  3. Inner-Outer DC Blocks features two capacitors in series with the inner and outer conductors.

Hughes Electronics DC Blocks are ideal for use in test and measurement environments, RF and microwave systems and communication systems where undesired direct current streams into the system.
