300khz-18Ghz dc block with N connecter

300 kHz–18 GHz DC Block with N Connector (Leader-MW)

The Leader-MW 300 kHz–18 GHz DC block is a wideband RF component designed to isolate DC bias and low-frequency interference while allowing RF signals to pass with minimal attenuation. Covering an exceptionally broad frequency range from 300 kHz to 18 GHz, this DC block is ideal for applications spanning HF, VHF, UHF, microwave, and into the Ku band.

Engineered with precision coaxial construction and standard N-type connectors, the device offers excellent insertion loss and return loss characteristics across its entire operating bandwidth. It effectively blocks DC and low-frequency currents while maintaining superior signal integrity, making it essential for protecting sensitive test equipment, amplifiers, and receivers from unwanted DC offsets and ground loop currents.

The robust N-connector interface ensures reliable, repeatable connections in both laboratory and field environments, with high power handling capability and stable performance under varying conditions. Its compact, durable housing provides excellent shielding and long-term mechanical reliability.

Ideal for use in test-and-measurement setups, communication systems, radar, and satellite equipment, the Leader-MW 300 kHz–18 GHz DC block delivers dependable performance, broad frequency coverage, and cost-effective value—making it a versatile solution for engineers working across a wide spectrum of RF and microwave applications.
