Radio frequency RF PCB:

Radio Frequency (RF) is an abbreviation for Radio Frequency, which means the electromagnetic frequency that can be radiated into space, ranging from 300KHz to 300GHz. RF radio frequency is RF current, which is an abbreviation of high frequency AC change electromagnetic wave. An alternating current that changes less than 1000 times per second is called a low-frequency current, and a frequency of more than 10,000 times is called a high-frequency current, and a radio frequency is such a high-frequency current. High frequency (greater than 10K); radio frequency (300K-300G) is the higher frequency band of high frequency; microwave frequency band (300M-300G) is the higher frequency band of radio frequency.

In the theory of electronics, a current flows through a conductor, and a magnetic field is formed around the conductor; an alternating current passes through the conductor, and an alternating electromagnetic field is formed around the conductor, called an electromagnetic wave. When the electromagnetic wave frequency is lower than 100khz, the electromagnetic wave will be absorbed by the surface and cannot form an effective transmission. However, when the electromagnetic wave frequency is higher than 100 kHz, the electromagnetic wave can propagate in the air and be reflected by the ionosphere at the outer edge of the atmosphere to form a long-distance transmission capability. We refer to high-frequency electromagnetic waves with long-distance transmission capability as radio frequency; radio frequency technology is widely used in the field of wireless communication, and cable television systems use radio frequency transmission.
