Key Specifications/ Special Features
Radio frequency (RF) is the abbreviation of Radio Frequency, which represents the electromagneticfrequency that can be radiated into space, and the frequency range is from 300kHz to 300GHz, or evenlower, Radio frequency is radio frequency current, referred to as RF, which is the abbreviation of highfrequency alternating electromagnetic wave. The alternating current that changes less than 1,000 times persecond is called low-frequency curent, and the one that changes more than 10,000 times is called high-frequency current, and radio frequency is such a high-frequency current Radio frequency (300K-300G) is ahigher frequency band of high frequency (greater than 10K), and microwave frequency band (300M-300G)is a higher frequency band of radio frequency.
