Product Summary

MRF49XA is an ISM band sub-GHz RF transceiver. The MRF49XA is an ideal choice for low-cost, high-volume, low data rate (<256kbps) , two-way, short range wireless applications. The MRF49XA has a low phase noise and provides an excellent adjacent channel interference, Bit Erro Rate (BER) and larger communication coverage along with higher output power.
