High-power ASR6601 LoRa Module with PA & TCXO (433/470Mhz)
Product Description
433MHZ/470MHz High-power SOC Wireless LoRa Module with ASR6601 Chip
The DL-A6601PA-B module integrates a Power Amplifier internally, with a maximum TX power of 30dbm, which can effectively improve link budget, thereby improving communication quality and distance. This LoRa module is also equipped with TCXO (Temperature Compensate Crystal Oscillator), which solve the problem of frequency deviation between communication parties caused by the instantaneous heat generated by PA, or the large temperature difference between high and low environments. At the same time, it can also achieve narrower bandwidth at room temperature, with higher sensitivity and stable communication.
As for the RF characteristic, compared to traditional modulation methods, its LORA modulation can greatly improve the RF performance in all aspects. The RX current is 7mA, and the highest sensitivity can reach up to -148dBm.
This LoRa module fully utilizes the ASR6601 chip’s anti-interference ability, its high sensitivity and low power consumption make this RF module excellent in long-range communication, which can be widely used in various wireless communication fields of the IoT industry, especially battery powered application, and long-distance communication projects.
Moreover, this LoRa module has 24 GPIOs, and the RF circuit of this LoRa module has been matched and optimized by professional equipment, which will guarantee its good performance under high power in such compact size. You can easily develop wireless products with stable performance and high reliability base on this RF module, without having a deep understanding of RF circuit design.
