Patent ID: 8773218

Claim:
A quadrature hybrid circuit comprising: a first rung having a first port, a second port, and a first passive electrical component; a second rung, coupled in parallel with the first rung, and including second, third, and fourth passive electrical components; a third rung, coupled in parallel with the first and second rungs, and including a third port, a fifth passive electrical component, and a fourth port; and a plurality of passive electrical components intercoupling the first, second, and third rungs; wherein: the quadrature hybrid circuit is configured to transform a source impedance at the first port into a load impedance at the second port, the source and load impedances being different from one another; and either the second passive electrical component is a capacitor coupled with ground and configured to provide an input reactance, and the fourth passive electrical component is an inductor coupled with ground and configured to provide an output reactance, or the second passive electrical component is an inductor coupled with ground and configured to provide an input reactance, and the fourth passive electrical component is a capacitor coupled with ground and configured to provide an output reactance.
