868/915Mhz High Power SX1276 LoRa Transceiver Module with Switchable TCXO & PA

868MHz/915MHz High Power Wireless LoRa Transceiver Module with SX1276 Chip

DL-SX1276PA-HF is a high-power Spread Spectrum LoRa Transceiver Module, which was developed by DREAMLNK based on Semtech's SX1276 RF chip. For long-range transmission and better coverage concern, a power amplifier (PA) is integrated in this LoRa™ module, which increases its output power up to +30dBm (1W), by more than three times on the basis of the original SX1276 RF chip. This LoRa module innovatively adds the function of adjustable output power (switchable PA), which can switch between high and low power. When PA is enabled, the TX power reaches +30dBm @ 868/915M, while TX power can be reduced to +13dbm, when PA is disabled (with better harmonic wave).

Meanwhile, this DL-SX1276PA-HF LoRa module is equipped with a TCXO (Temperature Compensated Crystal Oscillator), which is more stable in applications such as high temperature, low speed, and narrowband transmission. By using TCXO, the RF module can better approach the design 

performance of the SX1276 RF chip (-149dBm @ LoRa™), and significantly improve its receiving sensitivity. Combined with high output power, sufficient link budget, and advanced LoRa™ modulation technology, this LoRa module can achieve longer communication range, stronger anti-interference ability, and better stability.

This LoRa module adopts the new generation LoRa™ Modulation technology, it features with many other advantages, such as low power consumption, long transmission distance, strong anti-interference performance, high confidentiality and strong concealment. The output power can be configured by software (20dBm), and the maximum output power of the RF module can reach 30dBm when the software is set to 20dBm power. Compare with traditional modulation (FSK/GFSK) technology, this LoRa™ Modulation technology has higher bandwidth utilization, and obvious advantages in 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.
