Termaline® Series RF Coaxial Terminations
The 8890-300 2.5 kW, TERMALINE® Load Resistor Series are self-contained high-power 50 ohm coaxial transmission line terminations requiring no outside power source&nbs******bsp;additional equipment.
It provides accurate, dependable, and practically nonreflective termination for testing and adjusting transmitters
under nonradiating 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. Oil-assisted (vented) convection cooling for safe, continuous operation up to 2500W full rated power
