8890-300 Termaline® RF Coaxial Termination 2.5 kW Oil-Coole
Product Description & Specs
The Model 8890-300 TERMALINE?<sup>(R)</sup> Load Resistor is a self-contained high-power 50 ohm coaxial transmission line termination requiring no outside power source or additional equipment. It provides accurate, dependable, and practically non-reflective termination for testing and adjusting transmitters under non-radiating 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 2.4 GHz.
Rugged load for high power base station RF testing up to 2.4 GHz.
Oil-assisted (vented) convection cooling for safe, continuous operation to 2.5KW.
Shipped with LC connector installed. Compatible with all Bird QC connectors.
Simple but rugged design minimizes maintenance requirements.
