MTX3
868MHz band Narrow Band FM sub-miniature TX
The MTX3 transmitter module adds a totally new
sub-miniature form factor to the existing range of
Radiometrix ISM band devices. Using cutting
edge integrated RF devices, it offers multi
channel, low power narrowband operation in a
previously unobtainable size. It is ideally suited
to applications where existing wideband
modules have insufficient range and where
traditional narrowband
physically be too big to fit in.
