Transmission Line Equations — Lesson 1

This lesson covers the fundamentals of microwave integrated circuits, focusing on microwave engineering. It delves into the field of electrical engineering, dealing with signals having a frequency range. The lesson explains the key aspect of microwave engineering, which is the wavelength of the signal. It also discusses the TEM, TE, and TM waves. The lesson further explains the distributed line effect and how to deal with a circuit with distributed elements. For instance, it uses the example of a long transmission line with series inductance and shunt capacitance to illustrate this concept.
