RF Transceiver Modules is a common technology in electronic engineering that is used to send and receive radio signals. It includes components such as transmitters, receivers, antennas, and other electronic equipment used for radio communication. BL620-ST is an RF transceiver module that has been designed for use in applications where extra long-range and high-power transmission is requred. It is widely used in applications such as remote monitoring, asset tracking, voice broadcast, and other applications that require long-range transmission and reception.

BL620-ST has a wide range of services which includes applications in communication & networking, medical solutions, electronics & automation, and industrial control. It is capable of transmitting and receiving radio signals in four frequency bands, namely 868MHz, 902MHz, 2.4GHz, and 5.8GHz. It also supports frequency hopping and digital modulation. In addition, the module has a low power consumption and small size, making it ideal for use in embedded and remote control applications.

The main working principle of BL620-ST is simple. It is a combination of two distinct sections; transmitter and receiver. The transmitter section consists of an oscillator, an amplifier, and an antenna. The oscillator generates the signal to be transmitted while the amplifier amplifies the signal power. The antenna, which is usually a wire loop or dipole, is used to send the signal to the receiver.

The receiver section consists of an antenna, a mixer, an amplifier, a demodulator, and a decoder. The antenna picks up the signal from the transmitter and sends it to the mixer, which combines it with the oscillator signal from the local oscillator. The received combined signal is then amplified and sent to the demodulator where the data is extracted. Finally, the decoder takes the data and decodes it to its original form.

Overall, BL620-ST is a powerful and reliable RF transceiver module which is suitable for a wide variety of applications such as remote monitoring, asset tracking, voice broadcast, and other applications that require long-range transmission and reception. It has a low power consumption and small size, making it ideal for embedded and remote control applications. It is capable of transmitting and receiving radio signals in four frequency bands and supports frequency hopping and digital modulation. The working principle of the module is based on the combination of two distinct sections; transmitter and receiver. Therefore, BL620-ST is a great choice for any application that requires the transmission and reception of radio signals.
