Full Solid-state Millimeter-wave Integrated Receiver Front-end Development,

In microwave and millimeter-wave systems, receiving front-ends play critical roles for the whole system performance. The theory and design for two channel Ka band solid-state integrated receiving front-end are discussed in this dissertation. This text is on the basis of introducing microwave components and parts basic theories in detail, develop Ka band receiving component, finish the first designed of the component.Chapter 1 presents a brief introduction of the millimeter-waves and their characteristics. Then, the development of microwave devices and integrated circuits is introduced. In addition, the martial requirement and development of receiving front-ends are discussed. Based on the principle and main technical indicators of Radar receiver, the schematic diagram and component index estimation of Ka band solid-state integrated receiving front-end are given. corresponding passive circuit and solid state circuit are analyzed in following chapters.Chapter 2 is concerned with passive circuits of this project, including waveguide -fin line-microstrip probe transitions and 1 -to-3 Wilkinson power divider, simulated after analyzed theoretically. A new configuration of microstrip Hairpin bandpass filter is presented. The result of the simulation and measurement has proved the method validity.Chapter 3 ,chapter 4 and chapter 5 is about solid circuits used in the project, such as low noise amplifiers, power amplifiers, single-ended mixers, single-balanced mixers, double-balanced mixer, involving principles, characteristics and the design. The needed chips were chosen according to the actual circumstances.Chapter 6 realized the Ka band solid-state integrated receiving front-ends. Provide the design principle of this component according to the specification requirement for this subject, then explained respect of receiving the making, assembly of the component and testing etc. separately.Finally, test data indicate receiving front-ends component that subject develop this meet the specification requirement basically, and has proposed improving the scheme to the weak point. It gives some improvement advise and easily ignored points that can provide important experience for later research on it.
