This paper presents the design procedure, and implementation of a dual band planar quadrature hybrid with enhanced bandwidth. The topology of the circuit is a dual stage quadrature hybrid, which provides much larger flexibility to allocate the desired operating frequencies and necessary bandwidth than other previously published configurations. In this paper, small dual frequency transformers in two sections are used to modify conventional broad band hybrid coupler for having arbitrary dual band… CONTINUE READING
