RF (Radio Frequency) technology in detail for beginners. What is RF ? RF (Radio Frequency) refers to the electromagnetic signals that operate in the frequency range from around 3 kHz to 300 GHz. It's a type of wireless communication technology that's used in various applications, including telecommunications, broadcasting, wireless networking, and Analog | Embedded processing | Semiconductor company | TI.com RF signals behave differently across frequency ranges, and understanding these differences is crucial for designing efficient systems. At low frequencies, radio signals tend to have better penetration through obstacles, making them ideal for long-range communication systems. Mid-range frequencies balance penetration and data capacity, while high frequencies, like those used in 5G wireless networks, offer greater bandwidth but are more susceptible to attenuation and interference. For example ... Radio-frequency electrical currents are usually carried by specially-designed transmission line such as coaxial cable, as ordinary electrical cables would have high power loss. 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 that humans can hear (though ...
