CXT/CXR
Issue 1, 27 July 2012
Multi channel 25kHz NBFM remote control TX/RX
The CXT transmitter and CXR receiver
modules offer a multi channel, low power,
and reliable remote control data link. This
makes the CXT/CXR pair ideally suited to
those low power applications where
existing
wideband
modules
have
insufficient range, or where low cost multi-
channel operation is needed without
compromising on RF specification or
regulatory requirement.
