The RFM95W-915S2 from Hoperf is a Lora™ RFM95W transceiver module at 915MHz band in SMD package. It feature LoRa™ long range modem that provides ultra long range spread spectrum communication and high interference immunity whilst minimising current consumption. Using patented LoRa™ modulation technique RFM95W can achieve a sensitivity of over -148dBm. The high sensitivity combined with the integrated +20dBm 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. Device also support high performance (G)FSK modes for systems including WMBus, IEEE802.15.4g. The RFM95W deliver exceptional phase noise, selectivity, receiver linearity and IIP3 for significantly lower current consumption than competing devices.

The RFM95W-868S2 transceivers features the LoRa™ long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.

The RFM119W/RFM119SW is a high performance, highly flexible, low-cost, single-chip (G)FSK/OOK transmitter for various,240 to 960 MHz wireless applications. It is a part of the HOPERF NextGen RFTM family, which includes a complete line of transmitters, receivers and transceivers. The RFM119W/RFM119SW provides the simplest way to control the data transmission. The transmission is started when an effective level turnover is detected on the DATA pin, while the transmission action will stop after the DATA pin holding level low for a defined time window, or after a
two-wire interface (TWI) command is issued. The chip features can be configured in two different ways: setting the configuration registers through the TWI, or programming the embedded RFPDK. The device operates from a supply voltage of 1.8 V to 3.6 V, consumes 27.6 mA (FSK @ 868.35 MHz) when transmitting +10 dBm output power, and only leak 20 nA when it is in sleep state. The RFM119W/RFM119SW transmitter together with the CMT2219A receiver enables a robust RF link.
