Application of an Arbitrary 6-Port Junction to Power-Measurement Problems

An analysis of an arbitrary 6-port junction, four ports of which are terminated by power meters, shows that the net power input (or output) at either of the remaining ports is a linear function of the four power meter indications. The validity of this result has been experimentally demonstrated at 10 GHz. This device promises to be a useful tool in a wide variety of power measurement and calibration problems.
