PartNumber: RFM95

Details: Description The RFM95W-868S2 transceivers features the LoRa long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. Using the patented LoRa modulation technique RFM95 can achieve a sensitivity of over -148dBm using a low cost crystal and bill of materials. The high sensitivity combined with the integrated +20 dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness. LoRa also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity and energy consumption. These devices also support high performance (G)FSK modes for systems including WMBus, IEEE802.15.4g. The RFM95 deliver exceptional phase noise, selectivity, receiver linearity and IIP3 for significantly lower current consumption than competing devices. Features Programmable bit rate up to 300 kbps Low RX current of 10.3 mA, 200 nA register retention Fully integrated synthesizer with a resolution of 61 Hz FSK, GFSK, MSK, GMSK, LoRaTM and OOK modulation Built-in bit synchronizer for clock recovery Preamble detection 127 dB Dynamic Range RSSI Automatic RF Sense and CAD with ultra-fast AFC Packet engine up to 256 bytes with CRC Built-in temperature sensor and low battery indicator RF Transceiver Applications: Automated Meter Reading, Wireless Sensor Networks, Wireless Alarm & Security Systems FAQs: 1: What`s the difference between RFM95 & RFM95W? A: “W” for overseas market. RFM95 = RFM95W, only marking different. 2: Why the chip on RFM95W module is RFM96, is it correct? A: Yes, it is correct, you can see the module number (RFM95W) on its back.
