General description
The CDP-TX-02E-R and CDP-RX-02E-R are a RoHS compliant FCC approved embedded industrial
narrowband FM radio transmitter and receiver.
They are suitable for various application fields such as wireless data communication, telemetry or
wireless security systems. They are easy to use and integrate into application systems.
Both CDP-TX-02E-R and CDP-RX-02E-R are equipped with a frequency synthesizer system with
micro controller. Available frequency ranges are from 457.5 MHz to 457.8875 MHz (32 channels: 16
ch x 2 groups). The compact size, low operating voltage and frequency selectability of the CDP-
TX/RX-02E-R make it ideal for various applications where its interference rejection and practical
distance range is far better than similar RF modules based on wide band SAW-resonator frequency
generators.
