UHF Narrow Band FM Transmitter & 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
