8891-320

5kW Oil-Cooled RF Termination

8891-320, Oil-Cooled RF Load is a self-contained high-power 50 ohm coaxial transmission line termination with an attached 230 VAC blower unit which provides forced-air cooling. The unit provides accurate, dependable, and practically non-reflective termination for testing and adjusting transmitters under non-radiating conditions.

The load consists essentially of a cylindrical film type resistor immersed in a dielectric coolant. The resistor, individually selected for its accuracy, is enclosed in a special tapered housing which provides a linear reduction in surge impedance directly proportional to the distance along the resistor.
