RF DC blocks

At IPRECE, we offer a versatile selection of DC Blocks—purpose-built coaxial components that effectively block DC currents while allowing RF signals to pass with minimal interference. Benefiting from over 30 years of RF and microwave engineering expertise, our DC Blocks are trusted for their performance and reliability across test & measurement, broadcast, telecom, aerospace, and laboratory environments.

Why Choose Our DC Block Solutions

• Effective DC isolation in RF signal paths, designed to protect sensitive circuits and improve system integrity.
• Multiple configurations available:
  • Inner DC block
  • Outer DC block
  • Inner/Outer (dual) DC block
• Varied connector types, including options like BNC and N-Type Male to Female—adaptable to multiple system interfaces.
• Reliable RF performance across a wide frequency band (e.g., 10 MHz to 4 GHz) with low insertion loss (~0.5 dB) and excellent VSWR (max 1.35)
• Robust construction suited for challenging industrial and laboratory environments—you can request customization based on specific installation needs.

Applications of DC Blocks

Our DC Blocks are ideal for:

• Preventing DC bias or leakage from entering RF circuits—vital for protecting amplifiers, receivers, and measurement equipment.
• RF test setups, enabling safe disconnection/reconfiguration without exposing instrumentation to unintended DC.
• Lab environments and broadcast/tower top equipment, safeguarding against DC-induced faults or damage.
• Any scenario requiring precise DC isolation while maintaining clean RF transmission.

Product Highlights

• BNC DC Block – Outer, 10 MHz to 4 GHz, 0.5 dB insertion loss, 200 V rating, –65 °C to +125 °C
  Ideal for test setups and modular systems that use BNC connectors.
• N‑Type DC Block – Inner/Outer, Male to Female, 75 Ω
  Flexible option suited for RF chains requiring full coaxial shielding and DC isolation.

Custom DC Block Options

At IPRECE, you can request specific configurations tailored to your design:

• Choice between inner-only, outer-only, or dual (inner/outer) DC isolation
• Connector type selection—e.g., BNC, N-Type—or custom interface on request
• Tailored electrical performance adjustments (frequency range, voltage rating, insertion loss)
• Mechanical adaptations for rugged or specialized installations

Quality & Testing

Each DC Block undergoes comprehensive validation:

• RF performance testing, including verification of insertion loss, VSWR, and impedance accuracy
• Voltage endurance testing to ensure reliable DC isolation capability
• Environmental testing across temperature extremes from –65 °C to +125 °C
• Full documentation and traceability, providing confidence for use in regulated and mission-critical systems
