   Radio frequency ( RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency [1] range from around 20 kHz to around 300 GHz. This is roughly between the upper limit of audio frequencies and the lower limit of infrared frequencies, and also ...

5. People also ask

   How does RF work?

   • “RF” refers to the use of electromagnetic radiation for transferring information between two circuits that have no direct electrical connection. Time-varying voltages and currents generate electromagnetic energy that propagates in the form of waves. We can wirelessly transfer analog and digital data by manipulating and interpreting these waves.

   What is RF design?

   • We see, then, that RF design is not about merely generating EMR; rather, RF design is the art and science of generating and manipulating and interpreting EMR in a way that allows you to reliably transfer meaningful information between two circuits that have no direct electrical connection. Why EMR?

   What is RF spectrum?

   • The RF spectrum can be defined as electromagnetic waves cycling between 3 Hz and 3,000 GHz, giving it a wide range of characteristics and use cases. Consider that a 3 Hz carrier produces three full electromagnetic waves per second and that the modulated signal that “rides” on this carrier is typically of a slower frequency.

   What are medical applications of RF energy?

   • Medical applications of radio frequency (RF) energy, in the form of electromagnetic waves ( radio waves) or electrical currents, have existed for over 125 years, and now include diathermy, hyperthermy treatment of cancer, electrosurgery scalpels used to cut and cauterize in operations, and radiofrequency ablation.
