Bird 8765 – Water Cooled RF Termination (40 kW)

• Designed as a compact, low VSWR, and non-radiating termination
• Used with high-power transmitter and transmission line systems
• Power Rating: 40kW Continuous
• Frequency Range: 1kHz – 900 MHz
• Connector: 3-1/8 EIA Flanged

The Bird 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.

• Power Rating: 40kW Continuous
• Frequency Range: 1kHz – 900 MHz
• VSWR: 1.10 (max)
• Impedance: 50 Ohms
• Water Flow Rate & Temp.:
• 7 GPM (26 lpm) @ +5°C
• 9 GPM (34 lpm) @ 60°C
• Water connection: ¾” std. hose thread
• Connector: 3-1/8 EIA flanged
• Coolant: water cooled

When used in conjunction with a Bird Model 6810 Series Thruline Wattmeter or 3127 Series Panel Meters, these RF load resistors may be used for direct reading power measurements up to 40 kilowatts.
