Abstract
An electromagnetic signal processor is disclosed comprising an input waveguide, an intermediate waveguide, and an output waveguide. The intermediate waveguide comprises two portions having substantially equal electromagnetic impedances. The two portions of the intermediate waveguide are coupled to each other at a first and a second junction. The input and output waveguides are electromagnetically coupled to the intermediate waveguide at the first and the second junctions, respectively. Electrically coupled to the intermediate waveguide is a semiconductor device responsible for processing input electromagnetic signals. The input waveguide functions to receive and direct an input electromagnetic signal to the first junction of the intermediate waveguide. At the first junction, the intermediate waveguide separates the input signal into two signals having substantially equal amplitudes. Each of the separate signals propagates along one of the two portions of the intermediate waveguide and as they propagate, the separate signals are processed by the semiconductor device. At the second junction, the separate signals recombine to form a single output signal and this output signal is transmitted via the output waveguide.
