"Superheterodyne receivers" article has been uploaded to the RF Design Guide page

Engineers looking at documentation for radio modules may not be familiar with the superheterodyne architecture and terms such as "IF frequency". Even though it does not affect how the radio is used, it is useful that engineers understand the meaning of the values behind these parameters and how they are decided in order to maximise receiver performance.

Upon reading the following article, engineers should be able to better understand this kind of radio architecture commonly found printed in the module operation guides and other technical documentation.
