Abstract :
The principles underlying the design of a wide-band dummy load are discussed. An example is described which has a purely resistive input impedance of 75 ohms at all frequencies above 100 Mc/s and is capable of measuring powers up to 1 kW with an accuracy of ± (2¿% of measured power +3 watts). It consists of a short coaxial line, filled with carbon tetrachioride, the inner conductor being made up from short sections of thin gold-film resistors.
