RFM119W 315MHz /433MHz /868MHz /915MHz OOK and (G)FSK transmitter

Descriptions
The RFM119W 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 NextGenRFTM family, which includes a complete line of transmitters, receivers and transceivers. The RFM119/S 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 1.8V 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.
