Title:
DIRECTIONAL COUPLING-TYPE MULTI-DROP BUS
Document Type and Number:
WIPO Patent Application WO/2013/121996
Kind Code:
A1
Abstract:
The invention relates to a directional coupling-type multi-drop bus, with impedance matched to the bus and speed increased, during coupling. A directional coupler is configured when a second module provided with a second coupler end is mounted in a first module provided with a first coupler end, so that a coupling impedance reflecting a proximity effect in a coupling state of a directional coupler is made to match the impedance of the bus.
