Abstract
A system and method is provided for crosstalk reduction in a coupled transmission line on a multilayer structure. The coupled transmission line provides a high frequency signal such as from a local oscillator to an electronic component such as a mixer. The signal carried by the coupled transmission line may be buffered and asymmetrically tapped. The coupled transmission line may have individual parallel lines extending in the direction of current flow. The lines may carry current in opposite directions. Each line contains strips and/or is disposed on a different metallization layer. Strips on each metallization layer (before being routed to another metallization layer) may carry current in opposite directions and overlying strips on different metallization layers may carry current in opposite directions. Multiple strips of an individual line present on a single metallization layer may be disposed symmetrically around a centerline of the coupled transmission line.
