DL-SX1278PA is a high power 433Mhz LoRa Transceiver Module, which was developed based on Semtech's RF chip SX1278. For long-range transmission and better coverage concern, a power amplifier (PA) and a low noise amplifier (LNA) are integrated into this LoRa module, which makes its output power up to 30dBm (1W) and receiving sensitivity up to -149dBm

433MHz Wireless LoRa Transceiver Module with SX1278 Chip 


DL-SX1278PA is a high power 433Mhz LoRa Transceiver Module, which was developed by DREAMLNK based on Semtech's RF chip SX1278. For long-range transmission and better coverage concern, a power amplifier (PA) and a low noise amplifier (LNA) are integrated in this LoRa module, which improves its output power (up to 1W) by more than three times of the original SX1278 chip. Meanwhile, its receiving sensitivity has been greatly improved, with its sufficient link budget and advanced LoRa™ spread spectrum technology, this LoRa Module can achieve a longer transmitting distance. 


The output power can be configured by software, and the maximum output power of the module can be up to 30dBm. Compare with traditional modulation (FSK/GFSK) technology, this LoRa™ Modulation technology has obvious advantages in receiving current, receiving sensitivity, transmitting power, receiving rate range and anti-interference ability. It solves the problems of Transmission Distance, Anti-interference, Signal Blind Angle and Power Consumption that the traditional modulation cannot take into account at the same time. 


With the help of LoRa™ Modulation technology, this DL-SX1278PA RF Transceiver Module can achieve Max. -149dBm@LoRa receiving sensitivity. It has more concentrated power density and better stability, with also many other advantages, such as low power consumption, long transmission distance, strong anti-interference performance, high confidentiality and strong concealment.

 

Features

● Support multiple modulation methods: LoRa™, FSK, GFSK, MSK, GMSK, OOK,
