Abstract

The invention discloses a broadband strip line debugging structure with slow wave characteristics and a design method thereof. The broadband strip line debugging structure is applied to a multi-layercircuit board, the multi-layer circuit board comprises multiple layers of dielectric plates which comprise surface layers, middle layers and bottom layers, the surface layers and the bottom layers ofthe dielectric plates are provided with ground layers, the middle layers of the multiple layers of dielectric plates are provided with stripe lines, the debugging structure and the stripe lines are connected through vertical metal columns filled with metal, and the debugging structure has the slow wave characteristics. According to the invention, the strip line debugging of a microwave multi-chipmodule and the phase compensation are carried out without affecting the transmission performance such as a transmission effect, a return loss, insertion loss and port impedance.

Description

technical field [0001] The invention relates to the technical field of three-dimensional wiring microwave multi-chip module (MMCM) based on a stripline transmission system, and more specifically relates to the detection, debugging and phase adjustment of microwave signals transmitted by an inner stripline in the MMCM. Background technique [0002] With the rapid development of radar and communication technology, the three-dimensional packaging microwave multi-chip component (MMCM) technology based on microwave multilayer circuit board is widely used in miniaturized, lightweight, multi-functional and high-reliability microwave components and systems. By making full use of the inner layer space of microwave multilayer circuit boards, designers can greatly reduce the layout area of ​​the surface layer of the multilayer circuit board and improve the layout flexibility; in addition, compared with the surface layer microstrip line, the inner layer stripline can Achieve low dispers...
