Integrated multifunctional power division switch network assembly based on vertical interconnection technology

Abstract

An integrated multifunctional power division switch network assembly based on a vertical interconnection technology comprises radio frequency cavities and a digital signal processing circuit board. Signal transmission between the radio frequency cavities is vertically interconnected through copper silver-plated round wires. The digital signal processing circuit board is vertically connected with the radio frequency printed board through an insulating medium and a copper silver-plated round wire, so that the driving control of a chip is realized, the switching function of multiple paths of signals is completed, a radio frequency signal is input from the side surface of the radio frequency cavity and output from the top surface of the cavity, and the signal output realizes the external floating output of the radio frequency signal through a floating KK head. The radio frequency front printed board and the radio frequency back printed board jointly complete signal power distribution, multi-channel switch switching and straight-through transmission. The digital signal processing board adopts a floating low-frequency connector to complete the same horizontal plane with radio-frequency signal output, and can be in blind-mating interconnection with a rear-end TR assembly to complete direct signal distribution and transmission of the TR assembly and an antenna.

Problems solved by technology

One is to use the current integrated circuit technology to integrate the power division function into a chip and use it in conjunction with other active and passive circuits, but this technology is still in the research stage. The integration technology integrated in one chip can only be used in low-power systems at present, but due to the limited technical level, it cannot be applied in practical engineering, and at the same time, this integration solution is not suitable for the relatively high power use of the current radar front-end

The second is that under the current technical conditions, the size of the power splitter is reduced as much as possible by optimizing the electromagnetic structure, so as to meet the bottleneck encountered in the current radar development and realize the development of miniaturization and integration. However, this technical solution is affected by raw materials. Larger, cannot be well applied in practical engineering

[0004] Disadvantages of the existing technology: (1) The integrated circuit technology (SOC) is used to integrate the power splitter with other microwave circuits. This technology is currently limited by the technological level and still cannot be applied in engineering applications. At the same time, this technology cannot be applied to radar front-ends and other large power occasions; (2) The method of further reducing the size of the power divider by optimizing the electromagnetic structure cannot solve the interconnection relationship between various signals; (3) the optimization of the microstrip line transmission form can only It can further optimize the performance of the power splitter itself, which cannot well meet the needs of the high integration of various signals of the current radar.
