Embodiment Construction

[0028] Certain terms are used in the description and claims to refer to particular elements. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that the first device is coupled to the second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

[0029] The purpose of the present invention is to provide a m...

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.

Description

technical field [0001] The present invention relates to a circuit device for transmitting high-frequency signals, and in particular to a circuit device with a signal line transition element and an impedance transformer, wherein the signal line transition element The signal passes through multiple layers of a multilayer circuit carrier, and the impedance converter is electrically connected to the signal terminal of the signal line transition assembly. Background technique [0002] In a wireless network, connectivity and communication between devices is accomplished through an antenna in a transmitter or receiver to propagate desired signals or receive desired signals from other components of the wireless network. In radio communication systems, such as mmWave radios, discrete components are usually combined at a low integration level. Such systems typically utilize expensive and bulky waveguides and package-level or board-level microstrip structures to interconnect semicondu...
