RF and microwave basics 1

Part 1: RF and microwave basics introduction

Let us start with an overview of this training and introduce the topics.

RF and microwave basics 2

Part 2: Overview

Then we give more details of the Chapter 1, this is what you get here for free. We explain RF and microwave, describe what electromagnetic spectrum means and name the different frequency bands that are in use.

Part 3: RF propagation: Ripples on a pond

We explain RF propagation by using the picture of the ripple on a pond.

Part 4: Definition of RF and microwaves

Next is the definition of RF and Microwave while talking about wavelength, typical frequency bands and typical applications.
