HopeRF RF 65 Manual

Low Power Integrated UHF Receiver With -120dBm High Sensitivity
GENERAL DESCRIPTION
The RF65 is a highly integrated RF receiver capable of
operation over a wide frequency range, including the
3 1 5 , 433,868 and 915 MHz license-free ISM (Industry
Scientific and Medical) frequency bands. Its highly
integrated architecture allows for a minimum of external
components whilst maintaining maximum design flexibility.
All major RF communication parameters are programmable
and most of them can be dynamically set. The RF65 offers
the unique advantage of programmable narrow-band and
wide-band communication modes without the need to
modify external components. The RF65 is optimized for
low power consumption while offering high sensitivity and
channelized operation. TrueRF™ technology enables a
lowcost external component count (elimination of the SAW
filter) whilst still satisfying ETSI and FCC regulations.
