8765 – 40kW Water-Cooled RF Termination
40 kW, Water-Cooled RF Termination
The 8765, RF Load is designed as a compact, low VSWR and non-radiating termination for high-power transmitter/transmission line systems. It generates almost no ambient heat, making installation space minimal and convenient, in any position. The RF power is converted to heat in the hollow resistive film load resistor and directly absorbed by the water flowing through it.
Features
- Broadband water-cooled load for long-term RF dissipation when heat must be efficiently transferred away from the area
- 3-1/8 EIA Flange allows termination of full 40 kW up to 900 MHz
- Requires flow rate of up to 10 gallons (38 liters) per minute
