- Guide price:
This is a comprehensive on-line course covering RF and wireless basics. It provides all that is needed to understand the basic concepts of RF technology.
The course, Online RF and Wireless Basics, consists of over 5 hours of technical content in 64 individual lectures. In this way, the course can be approached in bite sized chunks, ensuring that it is possible to understand each topic before moving on to the next.
The course uses video delivery enabling everything to be easy to understand. It is presented by Chris Potter PhD who has an excellent delivery. He is able to explain the concepts in an easy to understand fashion while not talking down to the student, and also not shying away from the more in-depth concepts which he is able to convey very well.
The online RF and Wireless Basics course uses a minimum of mathematics and aims to give an appreciation for each concept, eliminating exhaustive and often unnecessary mathematical detail found in more formal university-level courses and reference books.
This online course includes:
Description of what RF is. This is put into context with information about the history of radio communications, from early transatlantic wireless telegraphy experiments made by Marconi through to mobile or cellular smartphones that are widely used today.
Descriptions of basic concepts including frequency, bandwidth, wavelength, electromagnetic waves, free space and multipath propagation, electromagnetic spectrum, attenuation, power, decibels (dB) and transmission lines.
Modulation: This includes a description of the latest digital modulation techniques forming the basis of modern wireless digital communications systems.
Multiple access schemes: This is a key concept required for mobile communications where multiple users need to have access to a single base station. Other topics included in this section of the RF and Wireless Basics course includes Multiple Input Multiple Output, MIMO.
Basic component building blocks: This section describes the building blocks and components used in modern RF transmitters and receivers. The functionality and key technical characteristics are explained for the major components used within RF systems. These include the RF mixer, oscillator, attenuator, coupler, duplexer, power amplifier, isolator-circulator, low noise amplifier LNA, filters, detector and number of different types of antenna.
Common RF transceiver architectures. This includes the classical superheterodyne receiver as well as a modern LTE MIMO integrated circuit transceiver, where most of the RF functionality is embedded within a single integrated circuit.
The importance of linearity in RF systems: This section of the online RF and Wireless Basics course covers the effects of non-linearity in RF blocks and systems. It explains the undesirable effects of non-linear behaviour, including AM-AM and AM-PM conversion, spectral regrowth and the perennial issue of intermodulation distortion in RF transceiver systems.
The course is well thought out and presented. RF expert Dr Chris Potter presents it and is sure to make it enjoyable and easy to understand.
