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.

RF and microwave basics 4

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.

RF and microwave basics 5

Part 5: Electromagnetic frequency spectrum

We look into the details of the electromagnetic spectrum and why the size of an antenna matters.

RF and microwave basics 6

Part 6: Attenuation of EM waves by atmosphere

Another important topic is how does the atmosphere influence an electromagnetic wave and the propagation.

RF and microwave basics 7

Part 7: Frequency allocations

Who is taking care of all these frequencies.and how is the spectrum allocated.

RF and microwave basics 8

Part 8: Microwave frequency bands

Different frequency bands have different designations. Unfortunately there is an old and new designation. Let´s check it out.

RF and microwave basics 9

Part 9: Distributed not lumped

How to use distributed circuits at radio frequencies and what to take into account by using coils or capacitors.
