Abstract


In the millimeter wave reception system, the merits of the performance of the low noise amplifier and mixer are essential parts, low noise amplifier has an important impact on the overall noise of the receiver system, while the mixer is used to achieve frequency conversion in the receiver function. Based on the needs of the application of millimeter wave systems, complete localization devices to design Ka-band high-level radioactive - mixer assembly, the component by a low-noise amplifier module with mixer module consists of two parts. In this paper, a suspended microstrip line and the finline plane and quasi-planar transmission line as a transmission medium, all localization devices, the key components in the receiver front-end hybrid integration technology. The main work of this article: the new rectangular waveguide - microstrip transition converter circuit theory analysis and design; engineering design and commissioning of the Ka-band low-noise amplifier; Ka-band mixer engineering design and commissioning; Ka-band high-level - mixer assembly FBI test. The mixer is designed in this paper finline suspended microstrip - a single balanced mixer structures, the finline circuit and suspension between microstrip lines constituting a 180 ° phase Results and mixer diodes in reverse parallel to the finline with suspended microstrip among. Mixer circuit used in the suspension microstrip low pass filter, band-pass filter, the waveguide - suspended microstrip probe transition, the introduction of the waveguide - finline transition circuit, analysis, design, processing and testing the In the second chapter, are introduced. The fourth chapter of the basic theory of the mixer, the main indicators, in the form of basic circuit described, combined with the design results in the second chapter of the mixer circuit structure design and processing, and test results. Low-noise amplifier module is another part of this article, selected according to requirements made of the low-noise amplifier chip, two cascaded low noise amplifier monolithic loaded in the back-to-back waveguide - microstrip transition circuit, according to the chip data design DC bias circuit and the final completion of the design and processing of a low-noise amplifier module. Chapter III of this article will main technical indicators of the low-noise amplifier, the design of low-noise amplifier, low noise amplifier chip selection and low noise amplifier module implementations described. In the second chapter, the article describes a new band-pass filter medium theory of phase-based, and simulation results are given and authentication methods. Above on the basis of this article is the final completion of the Ka-band millimeter wave - mixing components for high-level and detailed test results are given. Finally, according to the test results, presented some problems in the design to improve the program.
