RF Transceiver Modules

BGM111A256V21R

The BGM111A256V21R is a highly integrated RF transceiver module designed and used for easy and fast integration into RF applications. This module provides a complete system solution, including crystal, RF filters, RF amplifiers and all other necessary settings to enable operation in the 2.4GHz industrial, scientific and medical (ISM) band.

Application Field

The BGM111A256V21R module is primarily used in short-range, low-power, wireless audio and data transmission. It is a popular choice for applications such as Bluetooth Low Energy, Wi-Fi, ZigBee, and proprietary protocols. It can also be used in other applications such as home automation and industrial control systems.

Working Principle

The BGM111A256V21R module works on the principle of frequency-hopping spread-spectrum (FHSS). It transmits in bursts between two modes of operation, one where it is constantly receiving data and one where it is sending out data. The transmitter first sends out a preamble followed by a bit sequence comprising a header, a data packet and a checksum. This is followed by a gap period of up to several milliseconds during which the receiver receives the data and verifies it. If the receiver correctly receives and verifies the data, then the transmitter sends out another burst.

The FHSS technology employed in the BGM111A256V21R module helps to ensure robust and reliable long-range communication. The module also includes advanced error correction algorithms to overcome interference, fading and noise. This combination of technologies ensures reliable and secure data communication.

The BGM111A256V21R module supports a variety of different communication protocols, including Bluetooth Low Energy (BLE), ZigBee, Wi-Fi and proprietary protocols. It is also compatible with a variety of different radio solutions, such as MiWi and BLE. This makes it possible to use the module in a wide range of applications.

In addition, the BGM111A256V21R module is very small and can be easily incorporated into a number of different products. This makes it an ideal choice for low-power transmission solutions in a variety of different applications.
