DC Blocks

Narda-MITEQ manufactures and designs a line of coaxial DC Blocks that can be used at the input or the output of the amplifier to prevent loading of the bias voltages. Together, coupled with Narda-MITEQ amplifiers, these DC blocks provide complete system balance, and boast both superior performance and reliability.

These DC Blocks feature: ultra-broadband performance, low insertion losses, off-the-shelf delivery and compact designs.

Narda-MITEQ's DC blocks are typically used in the following applications: OC768 transmitters and receivers, general purpose test and measurement systems. Some options are available such as custom frequency bandwidths and different connector outputs.

Type N, SMA and 2.92mm, 0.10 GHz. to 18 GHz Inside and Inside/Outside

DC blocks (Audio Interference Suppressors) are coaxial components that prevent the flow of audio and direct current (DC) frequencies while offering minimum interference to RF signals. There are three basic forms of DC blocks. 'Inner only' models have a capacitor in series with the center conductor, 'outer only' models have a capacitor in series with the outer conductor, and 'inner/outer' models have capacitors in series with both the inner and outer conductors. The insulation material on the outer models is non-conductive. Applications include ground loop elimination, signal source modulation leakage suppression, system signal-to-noise ratio improvement, test setup isolation and other situations where undesired DC or audio current flows in the system.

• Broadband Frequency Ranges
• Suppresses DC through 100 kHz Leakage from External Signal Sources
• Low Insertion Loss
• Small Size, Light Weight

Since 1953, Narda-MITEQ has been customizing to our customers specific requirements. This can include new design efforts, modifications to existing designs for performance and mechanical needs, as well as additional testing and environmental screening.
