Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] The TSV-based broadband dual-frequency Wilkinson power divider of the present invention has a structure such as figure 1 , 2 As shown, the traditional power divider is realized at a single frequency point, and transformed into a low frequency point and a high frequency point. At the same time, the inductor is realized by TSV technology. Firstly, the traditional microstrip line structure is extended to a dual-frequency structure, and the characteristic impedance and isolation resistance of the first-order and second-order microstrip lines are obtained through the odd-even mode analysis method. Then use the matrix analysis method to convert the first-order and second-order microstrip lines into the form of inductance and capacitance, so far the lumped circuit diagram of the broadband dual-frequency power divider is obtained. In order t...

Abstract

The invention discloses a TSV-based broadband dual-frequency Wilkinson power divider, which comprises a first-order TSV inductor assembly, the first-order TSV inductor assembly is connected with a second-order TSV inductor assembly through a first-order capacitor assembly, and the second-order inductor assembly is also connected with a second-order capacitor assembly. According to the structure provided by the invention, the area of the power divider can be reduced, and meanwhile, the compactness of the power divider is improved.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional integrated circuits, and relates to a TSV-based broadband dual-frequency Wilkinson power divider. Background technique [0002] With the continuous advancement of science and technology, radio frequency identification technology has been developed very fast, the product categories are becoming more and more abundant, and the applications are becoming more and more extensive, which has involved all aspects of people's daily life. The power splitter is one of the important components and research hotspots of the RF front-end. It divides the input power into equal or unequal recording power. Controlled array radar, etc., so the power splitter has a wide range of applications in microwave systems. Its performance directly affects the energy distribution and transmission of the entire system. The Wilkinson power splitter not only has good amplitude and phase characteristics, but also has a ...
