2.5 kw, oil-cooled terminations
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 or 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
· compatible with all bird qc connectors
· overload thermoswitch p/n 8890-008 is optional. free assembly when ordered as a package.
