Bluetooth RF transceiver is an electronic devices that receive and demodulate radio frequency (RF) signals, and then modulate and transmit new signals. They are used in many different voice, video and data applications.

The Bluetooth RF transceiver consists of an antenna that receives the transmitted signal and a tuner that separates a specific signal from all other signals received by the antenna. The detector or demodulator extracts the information encoded before transmission. Radio technology is used to limit local interference and noise. To transmit the new signal, the oscillator generates sine waves, which are encoded and broadcast as a radio signal.

What is difference Bluetooth RF module and SoC module?

1. The RF module is also called the Bluetooth protocol stack module. An RF module (short for radio-frequency module) is a small electronic device used to transmit and/or receive radio signals between two devices. In an embedded system it is often desirable to communicate with another device wirelessly.

2. SoC means that single die has everything - processor, memory, peripherals, etc. A module is comprised of multiple chips and other components, all mounted on a printed circuit board. An SoC integrates a microcontroller, microprocessor or perhaps several processor cores with peripherals like a GPU, Wi-Fi and cellular network radio modems, and/or one or more coprocessors.

3. RF is different from the SoC series, the RF module does not have an MCU, and the protocol stack must run on the customer's platform.
