E90-DTU(230N27) free sample tcxo RS232/485 27dBm 230MHz narrow band transmission rf transceiver modem for IOT
E90-DTU is a wireless data transceiver with the function of digital data processing,digital modulation and demodulation
Product Descriptions
E90-DTU (230N27) is a data transmission station that adopts extremely advanced ultra-narrow band modulation technology. On the original basis, power amplifier (PA) and low noise amplifier (LNA) are built in, so that the maximum transmitting power reaches 500mW and the receiving sensitivity is also improved to a certain extent. Compared with the products without power amplifier and low noise amplifier, the overall communication stability is greatly improved.Different from analog FM stations and modems, digital radio provides transparent RS232/RS485 interface.
The station works in 170MHz frequency band and the communication distance can reach &km. Wireless digital radio as a medium of communication, as well as optical fiber, microwave, open wire, there is a certain scope of application: it provides some special conditions, private network monitoring signals in real-time and reliable data transmission, low cost, easy installation and maintenance, diffiraction capability is strong, flexible network structure, the coverage is far characteristic, suitable for some more and occasions, such as dispersion and complex geographical environment with PLC, RTU, rain gauge, level gauge and other data terminal is connected.
