RFM119W-433S1 (HOPERF)

The RFM119W-433S1 from Hoperf is a RFM119W FM transmitter module at 433MHz band in SMD package. The RFM119W is high performance, highly flexible, low cost, single-chip (G)FSK/OOK transmitter for various wireless applications. This RFM119W is a part of the HOPERF NextGenRF™ family which includes a complete line of transmitters, receivers and transceivers. It 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. It is used in remote fan controllers, infrared transmitter replacements, remote lighting control, remote keyless entry (RKE), wireless alarm and security systems.
