Course Overview Course Numbers: H7215X-100 Course overview This course introduces students to the concept of transmission lines, which forms the basis for understanding RF and microwave technology. Students will understand the need for transmission lines and also the complexities involved in dealing with high-frequency systems. What you will learn After completing this course, you will be able to: • Explain the need to enlarge the concept of simple hook-up wires to the more general theory of transmission lines • Describe the concept of characteristic impedance of a transmission line • Describe the relationship between characteristic impedance, termination impedance and reflections • Compute VSWR, return loss and reflection coefficient and convert among these measures of reflection Gain a better understanding of transmission lines Specifications Audience New college graduates, technicians and junior engineers entering the RF and microwave technology field whose responsibilities include product design, testing or manufacturing Prerequisites None Course length Half day Course format 100% lecture Delivery method To save you time and travel, this course is delivered at your site. Detailed course agenda Transmission line basics • Why do we need a special class for microwaves? • What are transmission lines? • Various wavelengths and their corresponding frequencies Characteristic impedance • Transmission lines versus regular hook-ups • Distance and propagation in a transmission line • Characteristic impedance • Basic transmission lines Terminating a transmission line • Infinite transmission line • Terminating a lossless transmission line - With a short and open - With its own characteristic impedance Reflections • Incident and reflected waves on a shorted line, an open line and on an arbitrarily terminated lin • Reflection coefficient Impedance and Smith chart • Gamma plane, plotting impedance • Plotting impedance on a rectangular plane • Smith chart
