HIGH FREQUENCY WIRING STRUCTURE, HIGH FREQUENCY MOUNTING BOARD, METHOD FOR MANUFACTURING HIGH FREQUENCY WIRING STRUCTURE AND METHOD FOR SHAPING WAVEFORM OF HIGH FREQUENCY SIGNAL

摘要

PROBLEM TO BE SOLVED: To appropriately shape a signal waveform even when a wire length of a wiring pattern is long.SOLUTION: A high frequency wiring structure 1 includes a branch wiring pattern 6 formed by branching from a predetermined place of a main wiring pattern 2 corresponding to a transmission line on which a high frequency signal is transmitted. The branching wiring pattern 6 is formed by continuously connecting a plurality of segments having characteristic impedance and segment length individually set, respectively. Specific characteristic impedance and segment length of the branching wiring pattern 6 are determined so that a reflection wave generated at the boundary of two adjacent segments in the branching wiring pattern is superimposed on a signal on the main wiring pattern and a waveform of the high frequency signal propagating the transmission line is formed at an observation point on the transmission line.
