XBP24BZ7UITB001J

RF (Radio Frequency) Transceiver Modules are electronic communication devices responsible for both sending and receiving radio signals. They are essential components in most wireless communication systems and are becoming increasingly popular in consumer electronics, such as Bluetooth controllers, Wi-Fi routers, and smart televisions. The XBP24BZ7UITB001J is a sub-GHz RF transceiver module from Microchip Technology Inc. It is designed for use in ISM (Industrial, Scientific and Medical) radio band applications such as industrial automation, home security, and low bit rate communication. This article will discuss the application field and working principle of the XBP24BZ7UITB001J.

Application Field

The XBP24BZ7UITB001J is a low-cost device that operates in the 868MHz and 915MHz ISM band. It features a high output power, up to +15.5 dBm, and a receiver sensitivity of -116dBm, providing excellent range and link budget. It has two operating modes, OTA (Over the Air) and LORA (Long Range), both of which enable reliable and secure communication with the help of forward error correction (FEC) and built-in 128-bit AES encryption. It has a wide operating temperature range of -40C to +105C and is well-suited for both indoor and outdoor environments. The built-in interfaces provide convenient connectivity with MCUs, such as the PIC microcontroller, through SPI or 2-wire UART.

Working Principle

The XBP24BZ7UITB001J is a transceiver module designed for ISM band radio applications. It uses a chip-scale, low-complexity, multi-standard RF transceiver IC to transmit and receive data. The IC is capable of operating in various modes, such as OTA and LORA, with a wide range of frequencies (868/915MHz).The RF transceiver module is designed with two ports. The first port is the antenna port, where signals from the transceiver’s base station are received and transmitted. The second port is connected to a MCU choosing the protocol for communication, configuring the RF context, sending/receiving data, and making other useful operations.The module operates according to FSK (Frequency Shift Keying) modulation. It consists of a frequency synthesizer which is an oscillator that generates a signal at the desired frequency. The output of the synthesizer is then applied to a mixer, which modulates the signal with a modulation signal from the MCU. The modulated signal is then amplified and transmitted over the air using the antenna port.For receiving data, the module uses the same frequency synthesizer and mixer, but the signal is demodulated instead of modulated. The received signal is amplified by a low-noise amplifier and sent to a baseband processor, which demodulates the signal and sends the data to the MCU.

Conclusion

The XBP24BZ7UITB001J is a low-cost, high-performance RF transceiver module designed for use in ISM bands. It features high output power and a wide operating temperature range, making it well-suited for industrial and outdoor applications. It uses FSK modulation to transmit and receive data, and also incorporates forward error correction and encryption for secure communication.
