Abstract

See full text

A circuit comprises a phase combiner and four output ports. The phase combiner adds an in-phase positive input and a quadrature positive input to obtain an in-phase positive output, adds an in-phase negative input and a quadrature negative input to obtain an in-phase negative output, adds the in-phase negative input and the quadrature positive input to obtain a quadrature positive output, and adds the in-phase positive input and the quadrature negative input to obtain a quadrature negative output. The four output ports, are respectively configured to output the in-phase positive output, the in-phase negative output, the quadrature positive output, and the quadrature negative output.
