NRX2B
UHF Narrow Band FM Receiver
The NTX2B transmitter and NRX2B receiver offer a low power, reliable data link in a Radiometrix SIL standard pin out and foot print. This makes the NTX2/NRX2B pair ideally suited to those low power applications where existing single frequency wideband UHF modules have insufficient range.
Features
