Microwave Power Combiners for Signals of Arbitrary Amplitude

摘要

Schemes for combining power from coherent microwave sources of arbitrary (unequal or equal) amplitude have been proposed. Most prior microwave-power-combining schemes are limited to sources of equal amplitude.rnThe basic principle of the schemes now proposed is to use quasi-optical components to manipulate the polarizations and phases of two arbitrary-amplitude input signals in such a way as to combine them into one output signal having a specified, fixed polarization. To combine power from more than two sources, one could use multiple power-combining stages based on this principle, feeding the outputs of lower-power stages as inputs to higher-power stages.
