Embodiment Construction

[0019] refer to figure 1 and figure 2 . A vertically integrated isolated transition power divider, comprising: lower surface ground 5, inner layer ground 6, upper surface ground 7, common port integrated coaxial 2 inserted into multilayer dielectric board 1, distributed and arranged around the common port integrated coaxial 2 The metallized via hole 4 is used to integrate the metallized via hole 4 at both ends of the coaxial 2 through the symmetrical common port. The two high-resistance matching striplines 10 between the layer ground 6 and the upper surface ground 7 are transitionally connected to two low-resistance matching striplines through two isolation striplines 13 that are symmetrically curved in the shape of a "ji" along the center. Stripline 11, two-way low-impedance matching stripline 11 respectively pass through two-way branch port stripline 12 back to the branch port of cascaded input and output ends, isolated stripline 13 isolates four-way coupled stripline of ...

Abstract

The invention discloses an integrated vertical isolation transition power divider, which aims to provide a power divider with compact structure, high isolation and low loss in which vertical transition and power distribution are combined into one. The present invention is realized through the following technical scheme: the two high-resistance matching striplines (10) etched between the inner layer (6) and the upper surface (7) are respectively separated by two pairs, symmetrical along the center Two "ji"-shaped isolated striplines (13) are transitionally connected to two low-resistance matching striplines (11), and the two low-impedance matching striplines pass through the back of the two branch striplines (12) respectively. To the branch port of the cascaded input end and output end, the four-way coupled striplines of the isolated stripline respectively cascade the two isolation resistors (14) on the back side. The smooth transition of the interlayer structure of the multilayer dielectric board (1) and the efficient distribution or synthesis of power are realized through impedance transformation.

Description

technical field [0001] The invention relates to an integrated vertical transition power splitter which combines vertical transition and power distribution (or synthesis) into one and has isolation. [0002] technical background [0003] With the rapid development of the communication industry, the demand for miniaturization, intelligence, multi-function and high integration of microwave and millimeter wave components is getting higher and higher. Traditional two-dimensional integrated circuits can no longer meet this demand. Three-dimensional integrated circuits Came into being. In a three-dimensional integrated circuit, circuit layout is usually performed on different planes of stacking, and then the circuits on different planes are vertically interconnected. Therefore, vertical interconnection is an important technology for 3D integration, and its performance directly affects the overall performance of components. At the same time, in many microwave and millimeter wave sy...
