FSK/GFSK Wireless Transceiver Module with Swiss AXSEM AX5043 Chip
Product Description
High-performance FSK Transceiver Module with Swiss AXSEM AX5043 chip
DL-RTA5043 is a 50mW narrowband (centralized power) wireless data transmission module based on AX5043 RF chip from Swiss AXSEM. It works in 433.92MHz ISM band and uses SPI port for data transmission, which reduces the cost budget for wireless applications.Narrow-band transmission has the advantages of concentrated power density, long transmission distance and strong anti-jamming ability, and greatly increases transmission distance compared with other similar products at the same power. The module can configure FEC forward error correction algorithm, which has high encoding efficiency and strong error correction ability. It can actively correct the jammed packets in case of sudden interference, greatly improving the reliability and transmission distance.
This RF module has data encryption and compression capabilities. The transmit data in the air is random but with rigorous encryption and decryption, which makes data interception meaningless.The data compression function has the probability to reduce the transmission time, reduce the probability of interference, and improve the reliability and transmission efficiency. The module can operate in the low voltage range of 1.8-3.6V to meet the needs of battery power supply. The module communicates with MCU via SPI port, can simulate SPI interface through standard SPI interface or I/O interface of MCU, consumes only tens of microamperes of current in power saving mode, and is very suitable for ultra-low power system and sensor application.
