Abstract
A circuit device includes a multilayer circuit carrier, a first signal transmission line, a second signal transmission line, a signal line transition element, a first impedance transformer, and a second impedance transformer. The multilayer circuit carrier includes a first layer and a second layer. The first signal transmission line is on the surface of the first layer. The second signal transmission line is on the surface of the second layer. The signal line transition element passes through the first layer and the second layer, and has a first signal terminal and a second signal terminal. The first impedance transformer is on the surface of the first layer and electrically connected between the first signal transmission line and the first signal terminal. The second impedance transformer is on the surface of the second layer and electrically connected between the second signal transmission line and the second signal terminal.
