Bird
50 kW, Water-Cooled RF Terminations
8770 Series, RF Loads are designed as compact, low VSWR and non-radiating terminations for high-power transmitter/transmission line systems. The units generate 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.
