250 Watt, Oil-Cooled Terminations
The 8141 Termaline® Load Resistor is a portable, self-contained general purpose 50 ohm coaxial transmission line termination 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. This produces the uniform, practically
reflectionless line termination from dc to 2.5 GHz.
Rugged portable Bench load for medium power base station RF testing up to 2.5 GHz
