Abstract

The invention discloses a miniaturized substrate integration waveguide duplexer which comprises a first metal copper coating layer, a first dielectric layer, a second metal copper coating layer, a second dielectric layer, a third metal copper coating layer, a third dielectric layer and a fourth metal copper coating layer which are stacked from the top down sequentially, wherein a dual-mode resonant cavity and triangular resonant cavities are defined by metallized through hole arrays; the dual-mode resonant cavity is connected with the triangular resonant cavities by coupling slots; the triangular resonant cavities are connected mutually by coupling windows; and a microstrip line structure is used for input and output. The duplexer can be used for microwave and millimeter wave communication systems, and has the advantages that the duplexer is suitable for system miniaturization, and is light in weight, low in cost, easy to integrate and fast in processing cycle.

Description

technical field [0001] The invention belongs to the technical field of microwave and millimeter wave passive devices, in particular to a substrate integrated waveguide duplexer in microwave and millimeter wave passive devices. Background technique [0002] With the rapid development of modern communication systems, the functions of microwave and millimeter wave circuits are becoming more and more complex, and the electrical performance requirements are getting higher and higher. At the same time, they are also developing in the direction of miniaturization, light weight, and low cost. This development trend is formed to meet the commercial requirements of microwave and millimeter wave circuits. The substrate integrated waveguide is a kind of transmission line structure with low loss, high power capacity, low cost and easy integration under this situation. Using this technology, high-performance filters, antennas, duplex Microwave and millimeter wave devices such as devices....
