Abstract : A method and system for making absolute measurements of coherent rf power is described. The method surmounts the primary shortcoming of the other existing methods in that it permits absolute measurement of power at all radio frequencies, whereas the other methods are inherently frequency limited, with the current upper limit being about 75 GHz. This major advantage stems from the fact that this method utilizes a direct comparison of the unknown rf power with a primary standard, whereas all other methods require a conversion of the power to heat before making the comparison.
