868MHz Wireless Transceiver Module with CMT2300 Chip 


DL-RTM300-868 RF Module was designed base on CMOSTEK CMT2300 wireless transceiver chip, it is Pin to Pin with HopeRF's RFM300-868S2 RF Transceiver Module. It is a compact, low-power, long-distance wireless transceiver module. It is set to 868MHz and other special frequency bands of the ISM band (433Mhz/915Mhz available). It has 140dB maximum link budget, and the maximum transmission rate can reach 300Kbps. The high receive sensitivity(–120dBm) coupled with +10dBm output power ensures extended range and improved link performance.

This 868MHz Wireless module integrates all RF-related functions. You do not need to have a deep understanding of RF circuit design, but easily develop wireless products with stable performance and high reliability...
