It’s used to allow full power output while testing or experimenting without radiating a radio frequency signal. Fan must be used at high power levels. Limited Time Sale Easy Return. Figure 1. Power Supply Dummy Load. Posted date: May 24, 2019 in: Antenna. The forward rf power from the klystron and reflected rf power from the SiC-dummy-load were measured with two Beth-hole couplers. An ingenious form of dummy load is a transmission line with conductors deliberately made from a high resistance alloy. A dummy load with 50 ohms gives your transmitter the proper resistance, protecting it at its final RF amplifier stage,so it is also called 50 ohm dummy load. The high power operation was carried out while monitoring the vacuum pressure, x-ray signal and rf power levels at various points in the system. A year and a half after building this dummy load, I hooked up my antenna analyzer and did a quick check: the impedance and SWR curves have not moved! High power dummy load banks serve multiple generating sets and act as test and exercise load for standby DG sets and an uninterruptible power supply. That means we can avoid using very expensive power components, such as high power variable resistors or rheostats. 5Pcs 100w 50ohm dummy load RF resistor RFP 100-50 TW power terminator Fad #gn. $10.26.
