Abstract:
1. A phase shift device comprising: an input quadrature junction configured to receive an input electromagnetic (EM) signal and extract a first EM signal, a second EM signal, a third EM signal, and a fourth EM signal from the input EM signal; a first waveguide arm operatively connected to said input quadrature junction to convey the first EM signal therethrough; a second waveguide arm operatively connected to said input quadrature junction to convey the second EM signal therethrough; a third waveguide arm operatively connected to said input quadrature junction to convey the third EM signal therethrough; a fourth waveguide arm operatively connected to said input quadrature junction to convey the fourth signal therethrough; wherein at least two of said first, second, third and fourth waveguide arms are configured to shift the phase of the first and third EM signals conveyed therethrough such that the first and third EM signals are phase shifted by about 180 degrees with respect to the second and fourth EM signals; and an output quadrature junction operatively connected to said first, second, third, and fourth waveguide arms to combine the first, second, third, and fourth EM signals and provide an output EM signal.
