LMT3

NBFM Multi-channel transmitter for 868MHz SRD band

The LMT3 is a 25kHz channel narrowband

multichannel transmitter offering up to 25mW RF

power. LMT3 can be paired with the Category 1

compliant receiver intended for European 869.2-

869.25MHz Social Alarm application. It can also be

used for any 868 - 870MHz band Non-Specific SRD

applications. The module offers a low power,

reliable data link in an industry-standard pin out and

footprint.
