8251D7-16, Oil-Cooled RF Load for Digital Broadcast is a portable, self-contained general purpose 50 Ohm coaxial transmission line terminations requiring no outside power source or additional equipment. The loads are Oil-assisted convection cooling for safe, continuous operation up to 1000 Watt full rated power. They provide 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. Specifications Power Rating: 0 - 1000W Continuous (No Blower) Frequency Range: DC - 2.4 GHz VSWR: (Measured using a N-Type Female Connector) DC to 1 GHz @ 1.1 to 1.0 1 to 2 GHz @ 1.25 to 1.00 2 to 2.4 GHz @ 1.3 to 1.0 Impedance: 50 Ohms Connector: 7/16 DIN Female Coolant: Oil-Cooled
