Abstract

The bend in a pair of differential transmission lines on printed circuit boards causes a path difference, which leads to mode conversion due to the phase difference. We previously proposed a tightly coupled asymmetrically tapered bend to suppress forward differential-to-common mode conversion. In this paper, we propose a design methodology of our tightly coupled asymmetrically tapered bend that limits the bend structure within the area of the original classic bend for high-density mounting. We also evaluated the 45-degree-angle bend formed based on our design methodology and found that the methodology helps improve or maintain its transmission characteristics compared to those of the classic bend.
