Conector coaxial tipo F Kathrein EMK 05

The Kathrein EMK 05 is an F-type coaxial terminating resistor with an integrated DC-block, designed for 75 Ω satellite IF distribution and general coaxial systems. It provides a screening factor greater than 85 dB and meets screen class A to minimize interference and maintain signal integrity across the 5–3000 MHz frequency range. The product is supplied as a single male F-type connector and is intended to block DC paths while matching system impedance.

Advantages

The EMK 05 combines termination and DC-block functions in one compact F-type male connector, reducing component count in distribution networks. Its high screening factor (>85 dB) and screen class A construction limit ingress and egress of unwanted signals. The 75 Ω impedance and wide frequency coverage (5–3000 MHz) make it compatible with standard satellite IF and a variety of audio/video coaxial applications.

Key specifications

How to use

Attach the male F-type EMK 05 to the female F connector of the coaxial cable or device port that requires termination and DC isolation. Ensure a clean, threaded connection and tighten by hand or with an appropriate torque tool if specified by installation guidelines. The integrated DC-block prevents DC current flow while the resistor provides the required termination to maintain 75 Ω system matching.

Recommendations

Use the EMK 05 where DC must be blocked—for example, when isolating legacy power-injecting equipment from passive downstream components. Verify mechanical fit and that system components expect a 75 Ω termination. Do not apply DC power through the terminated port; if DC continuity is required, select an appropriate non-blocking terminator.
