CDP-TX-05M-R and CDP-RX-05M-R are low power narrow band FSK transmitter and receiver modules, designed for industrial applications operating in sub 1-GHz. The modules contain most of the components necessary for radio transmission in compact cases. The RF channel is fixed but selectable within 4 preprogrammed channels. The receiver is double-superheterodyne and equipped with a SAW filter, ensuring high sensitivity and very good selectivity for stable and long range communication. The frequency table can be customized according to the customer’s requirements.
