50khz-67Ghz broadband DC block

The 50 kHz to 67 GHz broadband DC block from Leader-MW is a high-performance coaxial passive component engineered for ultra-wideband RF, millimeter-wave, and high-speed digital test applications. Spanning an exceptionally broad frequency range from 50 kHz up to 67 GHz, it effectively isolates DC bias voltages and prevents ground loops while allowing high-frequency signals to propagate with minimal attenuation.

Featuring precision 1.85 mm coaxial connectors and a standard 50 Ω characteristic impedance, the unit delivers consistent electrical performance across its entire bandwidth. Key specifications include low insertion loss (typically under 1.8 dB at upper frequencies), low VSWR (typically ≤ 1.6:1), and reliable DC breakdown voltage handling (often rated up to 16 V – 50 V DC).

Constructed with a compact, rugged passivated stainless steel body, this DC block ensures durability and stable phase performance in demanding environments. It is widely used in high-speed optical module testing, 112 Gbps / 224 Gbps PAM4 SerDes characterization, wideband receiver protection, and advanced microwave laboratory measurement setups.
