NiM2-xxx.xxx-10
UHF Narrow Band Transceiver
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.
Features

Conforms to ETSI EN 300 220-3 (radio) and EN 301 489-3 (EMC)
Standard frequency: 434.65 and 434.075MHz
Custom frequencies available in 433MHz (EU) band
Data rates up to 10kbps
Usable range over 500m
25kHz Channel spacing
Longer range compared to Wide Band FM modules

Available for licence-exempt operation in the 433MHz EU band, the NiM2 modules combine effective
screening with internal filtering to minimise spurious radiation and susceptibility thereby ensuring
EMC compliance. They can be used in existing low data rate (<10kbps) applications where the
operating range of the system using wide band transceivers need to be extended. Because of their small
size and low power consumption, NiM2 is ideal for use in battery-powered portable applications.
NiM2 is also available as separate NiM2T transmitter and NiM2R receiver, which can be used as dual-
in-line equivalents of NTX2 transmitter and NRX2 receiver respectively.
