Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the drawings and specific embodiments.

[0021] The present invention is a three-dimensional hairpin filter applied to 6G communication, with reference to figure 1 with figure 2 , Including a parallel arrangement of hairpin unit rows and upper ground RDL1, the hairpin unit row is composed of five hairpin units 2 arranged at intervals in a "one" shape, from left to right are hairpin unit I, hairpin unit II, Hairpin unit III, hairpin unit IV, hairpin unit V, hairpin unit I has a signal RDL22 at the top, four signals TSV21 at the bottom, and a signal RDL22 at the bottom of hairpin unit II and four signals TSV21 at the top. The upper and lower end structures of the hairpin unit III, the hairpin unit V and the hairpin unit I are the same, and the upper and lower end structures of the hairpin unit IV and the hairpin unit II are the same. The outer side of the signal TSV21 at the end of each hairpin unit...

Abstract

The invention discloses a three-dimensional hairpin filter applied to 6G communication. The hairpin filter comprises a hairpin unit column and an upper grounding RDL which are arranged in parallel, the hairpin unit column is formed by arranging a plurality of hairpin units at intervals; a signal TSV is arranged at one end of the hairpin unit; the other opposite end is a signal RDL; the upper and lower end surface structures of the adjacent hairpin units are opposite; symmetrical signal feeders are arranged at the tops of the two ends of the hairpin unit column. Signal RDLs are arranged on thetop surfaces of the hairpin units at the end parts of the two ends of the hairpin unit column; the top of the upper grounding RDL is provided with a grounding feeder line opposite to the signal feederline, the bottom of the upper grounding RDL is provided with a lower grounding RDL, a grounding TSV opposite to the signal TSV is arranged between the upper grounding RDL and the lower grounding RDL,and the signal TSV and the grounding TSV are embedded in the same silicon substrate. According to the three-dimensional hairpin filter, the design of the three-dimensional hairpin filter in the THz frequency band is successfully realized by adopting the TSV technology, and the return loss in the filter passband is improved by adopting the four-arm hairpin unit, so that the performance is improved.

Description

Technical field [0001] The invention belongs to the technical field of electronic communication, and relates to a three-dimensional hairpin filter applied to 6G communication. Background technique [0002] 5G communication technology has entered the commercial stage. It has a high-speed signal transmission rate and a wider channel. 6G communication technology is the inevitable trend of future communication technology development. 6G communication works in the THz frequency band. The working frequency range of THz is from 0.1THz to 10THz. The 2019 World Radiocommunication Conference (WRC-19) approved 275GHz-450GHz broadband resources to be used for mobile communication services. Among them, the 356GHz-450GHz band has the largest bandwidth and can provide the highest channel resources. As an important component of microwave communication, passive filters have always received extensive attention and applications. As a passive filter with simple structure, small size, low cost,...
