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.
