Oil-Cooled RF Terminations and Loads

Bird's Oil-Cooled RF Loads are self-contained high-power 50 Ohm coaxial transmission line terminations requiring no outside power source or additional equipment. These units provide accurate, dependable, and practically non-reflective termination for testing and adjusting transmitters under non-radiating conditions.

The loads consist of a cylindrical film type resistor immersed in a dielectric coolant. The resistor, individually selected for it's accuracy, is enclosed in a special tapered housing which provides a linear reduction in surge impedance directly proportional to the distance along the resistor.
