UHF Narrow Band FM Transceiver

NiM2 Transceiver

Frequency:434.65 and 434.075MHz

The narrow band NiM2 transceiver offers a low power, reliable data link in a Radiometrix transceiver standard pin out and footprint. This makes the NiM2 ideally suited to those low power applications where existing single frequency wideband UHF modules have insufficient range.
