What is an RF board?

Before understanding the RF board, let's first extend it to the baseband board. The baseband board is used to transmit signals, which are all fundamental frequency signals with very low frequencies. To achieve long-distance transmission, the fundamental frequency signal to be transmitted must be modulated onto the RF signal and then transmitted. Therefore, the RF board is used to transmit and receive RF modulation signals, and the RF frequency is much higher than the modulation signal frequency.

Generally, RF boards include main functions such as RF modulation, RF transmission, RF reception, RF demodulation, and RF control.
