Resistência terminal Televes FRC 750 — carga terminal coaxial de 75 Ω para sistemas de RF

Termination resistor Televes FRC 750 — 75 Ω coaxial load for RF systems is a compact passive device designed to terminate coaxial lines with a characteristic impedance of 75 ohms. It is intended for use in RF, broadcast and cable distribution systems where proper termination is required to prevent standing waves and signal reflections. The unit delivers a stable load across the applicable frequency range for typical television, radio and measurement applications, and its compact form factor allows for easy placement in test setups or in-line within distribution networks.

Advantages

The Televes FRC 750 provides a precise 75 Ω impedance match that reduces reflections and helps maintain signal integrity. Its coaxial design ensures compatibility with standard F-type and similar RF connector systems, offering low insertion loss and reliable passive behavior without the need for power. The device is built to be compact and robust for both temporary test use and permanent installation in confined racks or junction points.

Key specifications

How to use

Connect the Televes FRC 750 directly to the coaxial output or line that requires termination, ensuring a secure mechanical and electrical connection with the appropriate RF connector. For test and measurement tasks, attach the resistor to the device under test or to the unused port of splitters and combiners. Verify that the connection is consistent and that the surrounding network is compatible with a 75 Ω termination. No power or configuration is required; the unit functions as a passive load immediately upon connection.

Recommendations

Use the termination resistor in dry, indoor environments or in protected enclosures when installed in permanent distribution racks. Avoid exposing the unit to corrosive environments or heavy mechanical stress. For accurate RF measurements, ensure all connected equipment and cables are rated for 75 Ω systems and that connectors are tightened to prevent impedance discontinuities.
