Problems solved by technology

High-Q, low-loss, high-performance microwave filters can be produced by using microwave and millimeter-wave metal waveguides, but this kind of filter is firstly difficult to process and requires high processing accuracy; secondly, the production cost is relatively expensive; thirdly, this kind of filter The volume of the device is relatively large, and it is difficult to apply to the design of microwave and millimeter wave integrated circuits
Therefore, there is an urgent need for microwave and millimeter wave filters with high performance, small size, light weight, high Q value, low loss, low cost, and easy integration, so as to facilitate the design of microwave and millimeter wave integrated circuits; the fourth substrate integrated waveguide inductive communication The hole filter has good performance, small size, light weight, high Q value, low loss, low cost, and easy integration. However, since the diameter of the inductive through hole is limited by the production process, repeated optimization is required during design, which greatly increases the design difficulty.

Embodiment Construction

[0017] The substrate-integrated waveguide quasi-inductive through-hole filter of the present invention includes a metal patch 1, a dielectric substrate 2, and a metal through hole 3; the metal patch 1 is arranged on the dielectric substrate 2, and the metal patch 1 as the main body of the filter The middle part of the metal patch 1 is rectangular, and the two ends are symmetrically called "funnel"-shaped ports. Two rows of metal through-holes are respectively arranged along the sidelines on both sides of the rectangle in the middle of the metal patch 1, and a row of metal through-holes is arranged between the two rows of metal through-holes. The ring composed of many metal vias is the first quasi-inductive via, the second quasi-inductive via, the third quasi-inductive via, the fourth quasi-inductive via, the fifth quasi-inductive via, and the sixth quasi-inductive via , arranged along the direction of input end 4 and output end 5. The diameter D of the metal through hole 3 is ...

Abstract

This invention relates to base chip integration waveguide semi-inductive hole filter, which comprises metal slice, medium base chip and metal holes, wherein, metal slice is set on medium base chip; the metal slice of filter middle is of rectangle shape and two ends as funnel shape and with two rows of metal holes along rectangle shape two sides; there is set one row of metal holes between metal holes to form ring composed of first, second, third, fourth, fifth and sixth inductive holes along input and output ends.

Description

technical field [0001] The invention is a substrate-integrated waveguide quasi-inductive through-hole filter that can be applied to the design of microwave and millimeter wave circuits and can also be used in the design of microwave and millimeter wave integrated circuits. It belongs to the technical field of microwave filters. Background technique [0002] Microwave and millimeter wave filters in microwave and millimeter wave RF systems center of many design problems Such as in frequency converters, frequency multipliers, and multiplex communications. The electromagnetic spectrum is limited and must be allocated according to the application; and the filter can be used to limit the radiation of the high-power transmitter in the specified frequency band, and vice versa Can be used to protect the receiver from interference outside the operating frequency band. High-Q, low-loss, high-performance microwave filters can be produced by using microwave and millimeter-wave met...
