915MHz RF Transceiver Module with -120dBm Sensitivity and 1.8KM Range
DL-RTM300-915 RF Transceiver Module was designed base on CMOSTEK CMT2300 wireless transceiver chip, it is Pin to Pin with HopeRF's RFM300-915S2 RF Transceiver Module. It is a compact, low-power, long-distance wireless transceiver module. It is set to 915MHz and other special frequency bands of the ISM band (433Mhz/868Mhz 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 915MHz 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...
