8141 – 250 Watt, Oil-Cooled RF Termination
250 Watt, Oil-Cooled RF Termination
8141, RF Load 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 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 2.5 GHz.
Features
- Rugged portable Bench load for medium power base station RF testing up to 2.5 GHz
- Oil-assisted convection cooling for safe, continuous operation up to 250W full rated power
- Quick Change (QC) connectors to minimize the need for adaptors when making critical measurements
- Low-profile housing with handle and rubber feet for trouble-free operation in the most demanding environments
