Sub-GHz transmitter module
1. Descriptions of RF Transmitter Module RFM67W:
The RFM67W is a fully integrated transmitter which can operate in the 315, 434, 868 and 915 MHz licence free ISM bands.The RF transmitter module has two modes of operation, a conventional MCU controlled mode and a ‘standalone’ mode which enables the RFM67W to download configuration and messages from an E2PROM in response to a user input. Stand-alone mode makes the RFM67W ideal for miniaturized or low cost remote keyless entry (RKE) applications.
It also offers the unique advantage of narrowband and wide-band communication in a range of modulation formats.
The RFM67W offers high RF output power and channelized operation suited for the European (ETSI EN300-220-1), North American (FCC part 15.231, 15.247 and 15.249) and Japanese (ARIB T-67) regulatory standards.
