Abstract
A signal transmission system includes: a first signal line and a second signal line each making up a differential line; a first capacitive load mechanism disposed in a first region connected to the first signal line, the first capacitive load mechanism having a first capacitance value; and a second capacitive load mechanism disposed in a second region connected to the second signal line and to the ground point line, the second capacitive load mechanism having a capacitance value asymmetric with the first capacitance value. This signal transmission system suppresses an increase in mode conversion loss caused by component characteristics variations.
