Narrowband radio modules span 600 m with 10 mW

Low Power Radio Solutions announces new wireless modules from Circuit Design Inc., the leading producer of narrowband radio modules. The CDP-TX-02E-R and CDP-RX-02E-R radio modules are intended for use in wireless industrial products.

The CDP-TX-02E-R and CDP-RX-02E-R are housed in small, robust shielded cases and require only a small number of additional components to make a working radio system. Thy use narrow-band FSK modulation for high noise immunity, and the high-sensitivity receiver ensures stable operation even in weak signal fields. The modules achieve a line-of-sight communication distance of more than 600 m with only 10 mW power output. They also combine a very small footprint with HF characteristics that guarantee high reliability and resistance to mechanical vibration and shock.

The modules have CE approval for the European model and FCC approval for the US model. The frequency can be selected from 32 pre-programmed channels in 25-kHz steps or set to any desired channel. The modules have a wide operating temperature from -20°C to +60°C, suitable for indoor and outdoor use. With strong blocking performance and selectivity, the modules offer high reliability and stable operation even in high noise environments.

The main features of the new CDP-TX-02E-R / CDP-RX-02E-R feature selectable 1 mW / 10 mW RF output, battery operation capability (3 V @ 33 mA or 43 mA), double superheterodyne receiver with high sensitivity (-120 dBm for 12 dB SINAD / BER 1%) and blocking (84 dB ± 1 MHz), 60 dB adjacent-channel selectivity, TCXO-based temperature compensation, and stable operation with all high-frequency circuits enclosed in a case measuring 36 x 26 x 10 mm (transmitter) or 50 x 30 x 9 mm (receiver size).
