250 Watt Oil-Cooled RF Termination

8141, Oil-Cooled RF Load is a portable, self-contained general purpose 50 ohm coaxial transmission line termination requiring no outside power source or additional equipment. It 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. This produces the uniform, practically reflection-less line termination from DC to 2.5 GHz.
