RFM95/96/97/98W RFM95/96/97/98(W) - Low Power Long Range Transceiver Module V1.0 GENERAL DESCRIPTION The RFM95/96/97/98(W) transceivers feature the TM LoRa long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption. TM Using Hope RFs patented LoRa modulation technique RFM95/96/97/98(W) 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 TM 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 RFM95/96/97/98(W) consumption. These devices also support high performance (G)FSK modes for systems including WMBus, IEEE802.15.4g. The RFM95/96/97/98(W) deliver exceptional phase noise, selectivity, receiver linearity and IIP3 for significantly lower current consumption than competing devices. APPLICATIONS KEY PRODUCT FEATURES Automated Meter Reading. TM Home and Building Automation. LoRa Modem. Wireless Alarm and Security Systems. 168 dB maximum link budget. Industrial Monitoring and Control +20 dBm - 100 mW constant RF output vs. V supply. Long range Irrigation Systems +14 dBm high efficiency PA. Programmable bit rate up to 300 kbps. High sensitivity: down to -148 dBm. Bullet-proof front end: IIP3 = -12.5 dBm. Excellent blocking immunity. Low RX current of 10.3 mA, 200 nA register retention. Fully integrated synthesizer with a resolution of 61 Hz. TM FSK, GFSK, MSK, GMSK, LoRa 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.
