RFM65W
RFM65W ISM RECEIVER MODULE V1.2
GENERAL DESCRIPTION
`
The RFM65W is a low cost receiver module capable of
operation in 315,433,868 and 915 MHz license-free ISM
(Industry Scientific and Medical) frequency bands. All major
RF communication parameters are programmable and
most of them can be dynamically set. The RFM65W offers
the unique advantage of programmable narrow-band and
wide-band communication modes. The RFM65W is
optimized for low power consumption while offering high
sensitivity and channelized operation. Compliance ETSI and
RFM65W
FCC regulations.
In order to better use RFM65W modules, this specification
also involves a large number of the parameters and
functions of its core chip RF65's, including those IC pins
which are not leaded out. All of these can help customers
gain a better understanding of the performance of RFM65W
modules, and enhance the application skills.
