Abstract

The invention is suitable for the technical field of microwave and millimeter wave circuits, and provides a microstrip line vertical transition structure and a microwave device, and the structure is characterized in that a metal box body is provided with a transition cavity which penetrates through the upper and lower side surfaces; the metal box body is arranged between the two microstrip probe devices and is connected with the back surface of each microstrip probe device; the position of the strip line probe arranged on the back surface of each microstrip probe device corresponds to the position of the transition cavity; a microwave signal is transited to a medium internal transmission line from a microstrip line arranged on the front surface of one microstrip probe device through a first signal blind hole in the microstrip line, transited to the strip line probe through a second signal blind hole connected with the medium internal transmission line and then vertically transited to the strip line probe on the microstrip probe device on the opposite side in the transition cavity; the microstrip line vertical transition structure is simple in structure, easy to assemble and convenient to debug, and a high-frequency, low-loss and miniaturized microwave and millimeter wave vertical transition structure can be achieved.

Description

technical field [0001] The invention belongs to the technical field of microwave and millimeter wave circuits, and in particular relates to a microstrip line vertical transition structure and a microwave device. Background technique [0002] The microstrip vertical transition structure is an indispensable component in microwave and millimeter wave components. Various microwave and millimeter wave integrated circuits are widely used in modern wireless systems and radar systems. As the requirements for miniaturization become higher and higher, microwave and millimeter wave components are more and more widely used. [0003] In microwave and millimeter wave components, microwave signals between different cavities are often connected vertically. Vertical transition connections usually include RF connectors, RF cables, RF insulators, microwave transition blocks, and buttons. However, the existing vertical transition connection structures generally need to be customized according...
