8640B Series, 25 kW, Forced-Air Cooled Terminations are available in models to work with 115 or 230 volts at 50 or 60 Hz. This compact high-power 50-ohm termination efficiently dissipates up to 25 kW of RF over a wide frequency range up to 1 GHz. The RF input connector is located in the center of the side of the nearly cube-shaped unit.
Forced-air heat exchanger cooled load for high-power applications up to 1 GHz
Compact, low-profile design saves space in crowded transmitter sites
Interlock control circuit provides fail-safe protection of the transmitter and load resistor in the event of an ac power failure to the blower or coolant pump
