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 a vertical integrated isolation transition power divider, and aims to provide a vertical transition and power distribution integrated power divider which is compact in structure, high in isolation and low in loss. Two paths of high-resistance matching strip lines (10) etched between the inner layer ground (6) and the upper surface ground (7) are isolated from each other; two paths of n-shaped bent isolation strip-shaped lines (13) which are centrosymmetric are in transition connection with two paths of low-resistance matching strip-shaped lines (11); two paths of low-resistance matching strip lines respectively pass through branch ports of two paths of branch port strip lines (12) opposite to the cascade input end and the output end, and four paths of coupling striplines of the isolation strip line are cascaded with two opposite isolation resistors (14). Smooth transition of an interlayer structure of the multilayer dielectric plate (1) and efficient power distribution or synthesis are achieved through impedance conversion.

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...
