鸟牌Bird|5000W假负载8921 5 kW, Oil-Cooled Terminations Termaline® Series RF Coaxial Terminations The 8920 Series TERMALINE® Load Resistors 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 nonreflective termination for testing
and adjusting transmitters under nonradiating 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.
