Bandwidth Miniature Quadrature Branch line Coupler Design
Denis A. Letavin
Abstract
The article defines the design process of a compact coupler used in the microwave technology as a power divider or adder. It is shown that replacing quarter-wave cuts with electrodynamic structures makes it possible to reduce the size of the device with small losses in performance. On the basis of a field experiment, a good convergence of theoretical and practical results is shown. The size of the compact device is 69.9% less than the space on the printed circuit board.
