Introduction

ATZB-RF-212B-0-U is a subset of the RF transceiver modules offered by Atmel Corporation, one of the leading providers in the embedded systems industry. The module is specifically designed to enable highly reliable communication between end-to-end RF links. It helps in applications such as light automation, remote control, and security systems as it offers important features like frequency agility, low power consumption, and error-free communication without the complexity of additional hardware components.

Application Field

Atmel\'s ATZB-RF-212B-0-U is suitable for different systems with low-range communication, primarily in the industry of industrial automation and remote control. This module is an excellent choice for applications which require a reliable, low-cost, low-power and simple implementation over a the UHF band. ATZB-RF-212B-0-U is also used in other applications in industrial and commercial systems such as remote monitoring and control systems, remote and automated production lines, automatic meter readers (AMRs), as well as for military applications such as battlefield communications.

Working Principle

The ATZB-RF-212B-0-U is an ASK communication module based on the Atmel device AT86RF212B, which is designed to enable communication over the 868 MHz to 928 MHz UHF frequency band. It can be used as a base station, remote node, or as a point-to-point connection. The transceiver module uses input RF signals, converts them into digital signals and sends them to the on-board processor for processing. The module also transmits data from the processor to the antenna, and the designated receiver will receive the transmitted signals. The module\'s receiver uses a highly sensitive IF (Intermediate Frequency) filter to reduce the noise level and filtering out unwanted signals. All incoming signals are demodulated, filtered and decoded to obtain the original data.

ATZB-RF-212B-0-U achieves a range of at least 200 m when the antenna is mounted on the top of a building. Its well-proven ASK modulation method ensures an optimal link performance even in high interference environments. This module supports up to 60 kilobits/s RF data rates, and each radio link consists of two transceivers, one transmitting and one receiving.

Conclusion

ATZB-RF-212B-0-U is a high-performance solution for applications where reliable UHF link communication is desired. Its highly sensitive receiver is optimized for low power consumption, and its high transmission rate ensures reliable delivery of data. This transceiver module is ideal for applications that require low-cost, low-power and robust communication in noisy RF environments.
