5000 Watts DC to 1 GHz - QC Connectors
8920 Series, 5 kW Oil-Cooled RF Terminations
5 kW, Oil-Cooled RF Terminations
8920 Series, RF Loads are self-contained high-power 50 ohm coaxial transmission line terminations requiring no outside power source or additional equipment. The units provide accurate, dependable, and practically non-reflective termination for testing and adjusting transmitters under non-radiating conditions. The loads consist 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 reflectionless line termination from dc to 1 GHz.
