The forward rf power from the klystron and reflected rf power from the SiC-dummy-load were measured with two Beth-hole couplers. Figure 1. Figure 9: High power test stand of SiC-ceramic dummy-load. A dummy load is a resistor used to load any radio frequency generator/amplifier to simulate an antenna for testing purposes. 4SQ-8DIR antenna system. It’s used to allow full power output while testing or experimenting without radiating a radio frequency signal. 100W RF Dummy Load (SMA, DC-3GHz) are used in a wide variety of measurement systems; any port of a multi-port microwave device that is not involved in the measurement should be terminated in its characteristic impedance in order to ensure an accurate measurement. The load shall have a power rating of at least 5 W in continuous mode, and have a measurement connector to connect to instruments.

There are also dummy loads for power supplies, known as load banks. The four-square phased-vertical array if used by many contesters and DXers for oreration on the low bands. Power supplies. any impedance changes due to electromagnetic interaction will be simulated perfectly. The MOSFET technology keeps the input impedance to a minimum and enables the load to draw very high current even at very low voltages. Here is what they want me to do exactly : ''Design and build a dummy load with 50 ohm impedance for the interval of 100-1000 MHz.

In addition, VSWR is less than 1.05 over the full waveguide bandwidth. In fact, this series of terminations is designed for low, and medium as well as high power input. The 63200 series loads use a current closed loop design, and connects all power MOSFET devices in parallel to insure high accuracy load control with minimal drift (less than 0.15% of the current setting). It could be used as a Dummy Load too but you need to connect a 50ohm Resistor Load terminator with suitable power ratings to the output terminal of the attenuator. 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.
