900Mhz Flex Decoder Board
Our 900Mhz flex decoder board (version 1.0) comes with TCXO, URAT data output as well as OTA function. Our product employs the flex platform to receive all sorts of information as well as to switch on or off the electrical equipment and power supply. The flex platform is a ready public service platform, so there is no need for customers to use the transmitter. Additionally, the flex platform of this flex decoder board has higher operation speed in comparison with the pocsag type. In many countries, the wireless service is able to cover a whole city. Unlike the ordinary wireless receiving device, this product adopts the double-conversion superheterodyne. It features exceptional interference resistance and high receiving sensitivity. Our product is able to work in very critical environments.
