What is RF circuit design?

RF (Radio Frequency) circuit design involves the design and analysis of electronic circuits that operate in the radio frequency range (typically from 3 kHz to 300 GHz). These circuits are used in a wide variety of applications including wireless communication systems (e.g., cell phones, Wi-Fi, Bluetooth), radar systems, satellite communication, broadcast radio and television, and medical devices. RF circuit design often requires specialized knowledge and techniques to address challenges such as impedance matching, noise reduction, signal integrity, and minimizing signal loss, due to the high frequencies involved and the effects of parasitic components.
