**课程名称：** RF Concepts, Components and Circuits For Beginners **课程概述:** 本课程是为初学者设计的射频（RF）工程入门课程。射频是指从约20 kHz到约300 GHz频率范围内，交变电流、电压或电磁场的振荡速率。射频工程是将无线电波作为研究和应用的学科，其目的是创造能够接收和发送这些电磁波信号的技术和设备。 RF工程在航空航学、电信、军事、商业广播、电视和空间相关领域的工作人员中具有重要意义。我们日常使用的手机通信就依赖于射频技术，而RF工程师正是设计和实现支持4G和5G网络的技术人员。 本课程将涵盖RF工程中的重要概念、关键组件和电路，为学习更高级的RF工程和设计打下坚实的基础。 **课程主要内容:** 1. **RF系统介绍** 2. **整体视图：发射机/接收机框图** 3. **重要的模拟与数字调制方案** 4. **基础电子概念回顾** 5. **RF振荡器** 6. **混频器及其应用** 7. **RF滤波器** 8. **功率放大器** 9. **天线** 10. **阻抗匹配、反射功率与驻波比 (VSWR)** 11. **S（散射）参数** 12. **史密斯圆图与阻抗匹配** 13. **低噪声放大器 (LNA)** 14. **RF衰减器及其类型** 15. **软件定义无线电 (SDR) 介绍**
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field in the frequency range from around 20 kHz to around 300 GHz.Radio frequency engineering, or RF engineering, is the study and application of radio waves with the purpose of creating technology and devices that can both receive and send signals using these waves. RF engineering is an important component for those working in aeronautics, telecommunications, military services, commercial radio, television and space-related professions. People use radio waves to communicate on their cell phones, and RF engineers design and implementing the technology that supports 4G and 5G networks.This is a beginner course in RF engineering that addresses important concepts, components and circuits used in the RF engineering. This course will serve as a basis to move ahead and build upon more advanced concepts in RF engineering and designs. This course is divided into following sections:Section 1: Introduction to RF systemsSection 2: Bigger Picture: Transmitter/Receiver Block DiagramSection 3: Important Analog And Digital Modulation SchemesSection 4: Revision Of Some Basic Electronics' conceptsSection 5: RF OscillatorsSection 6: Mixer and its ApplicationsSection 7: RF FiltersSection 8: Power AmplifiersSection 9: AntennasSection 10: Impedance Matching, Reflected Power & VSWRSection 11: S (Scattering)-ParameterSection 12: Smith Chart And Impedance MatchingSection 13: Low Noise Amplifier (LNA)Section 14: RF Attenuators and their TypesSection 15: Introduction to Software Defined Radios (SDRs)
