Embodiment Construction

[0037] The implementation of the present invention will be described below through specific examples and in conjunction with the accompanying drawings.

[0038] The microstrip power distribution / synthesis network based on microwave multilayer circuits designed by the present invention is composed of three layers of microwave circuits, mainly including: three layers of laminated dielectric substrates (input layer, middle layer, output layer), two layers of prepreg, Input microstrip power splitter, quarter-wavelength annular microstrip resonator, probe between layers and dielectric cavity for power distribution.

[0039] The laminated dielectric substrate is Rogers RO4350, and the prepreg is Rogers RO4450F, both of which have similar dielectric constants and thermal expansion coefficients, and can be better compatible to ensure the stability of circuit operation. At the same time, Rogers RO4350 is a hard board, which ensures the mechanical strength of the device.

Abstract

The invention discloses a millimeter wave microstrip power distribution or synthesis device, and relates to the technical field of microwaves/millimeter waves, in particular to a microstrip power distribution/synthesis network of a multilayer microwave circuit. 50-ohm standard microstrip lines are adopted for input and output, so that the device can be easily integrated with other microwave devices; a multi-layer microwave circuit technology is adopted, so that miniaturization of a power distribution/synthesis network is realized; on one hand, the power distribution/synthesis network is more compact in structure and does not easily excite other parasitic modes (a high-order mode is easy to excite due to an overlarge substrate microstrip); and on the other hand, the use length of the microstrip line or the strip line is also reduced, so that the loss of the power distribution/synthesis network is remarkably reduced, and the possibility that the microstrip power distribution/synthesis network is applied to a microwave high-frequency band and even millimeter waves is created. The processing of the device is realized on the basis of the current mature multi-layer PCB manufacturing process, the production cost is lower, and the mass production is easy to realize.

Description

technical field [0001] The invention relates to the field of microwave / millimeter wave technology, in particular to a microstrip power distribution / synthesis network of multilayer microwave circuits. Background technique [0002] With the development of microwave technology, the market demand for miniaturization, low cost, and high integration of microwave electronic devices is increasing. Among them, microwave multilayer circuit technology is currently a highly respected solution. Power distribution / combination networks are widely used in various microwave electronic devices. Therefore, research and realization of power distribution / combination networks that are miniaturized, low-cost and easy to integrate with other microwave devices is an urgent problem to be solved. The traditional waveguide power distribution / combination network and quasi-optical power distribution / combination network are bulky, not easy to integrate with other microwave devices, and the production cost...
