The basic components of an RF communication system include a transmitter, a receiver, an antenna, and a propagation medium (free space, air, or another environment).
The transmitter sends the information, which is modulated using various schemes and encoding techniques.22 jui. 2023
An RF circuit is a special type of analog circuit operating at the very high frequencies suitable for wireless transmission.
One salient feature of an RF circuit is the use of inductive elements to tune the resonant circuit operation around a specific radio carrier frequency.
Basic Principles of Operations
RF Transmission: An RF signal is created by upshifting a low bandwidth (DC-like) signal to radio frequency by a radio transmitter.
RF reception: An RF signal is picked up by the antenna and downshifted to a low bandwidth (DC-like) signal by a radio receiver.
