Product Descriptions
Ra-08-P is a high-power LoRa module used for ultra long distance spread spectrum communication. The ASR6601 chip is a universal LPWAN wireless communication SoC that integrates an RF transceiver, modem, and a 32-bit RISCUMC. This MCU uses an ARM core and can operate at a frequency of up to 48MHz. The Ra-08-P module supports LoRa modulation and traditional (G) FSK modulation for LPWAN use cases; The transmitter also supports BPSK modulation and (G) MSK modulation, while the receiver supports (G) MSK modulation. On the basis of this technology, the module is equipped with a power amplifier (PA) and a low noise amplifier (LNA), with high sensitivity exceeding -137dBm, transmission power of+29dBm, long transmission distance, and high reliability. Meanwhile, compared to traditional modulation techniques, LoRaTM modulation technology also has significant advantages in anti blocking and selection, solving the problem that traditional design schemes cannot simultaneously consider distance, anti-interference, and power consumption.
The Ra-08-P module provides ultra long range and ultra-low power communication for LPWAN applications, which can be widely used in scenarios such as smart meters, supply chain and logistics, home building automation, security systems, remote irrigation systems, etc.
