Nagano, Japan: Circuit Design Inc has developed the CDP-TX-02E-R transmitter and CDP-RX-02E-R receiver as the successor models to the CDP-02 series industrial use radio modules. The products comply with the RoHS Directive that comes into force in Europe from July 1, 2006. The shape and interface of the new models, while reliability and stability have been enhanced. With the development of new circuits using TCXO, the minimum operating temperature has been expanded from -10ºC in the earlier models to -20ºC. RF output complies with the European ISM band RF power limit, and users can select either 10 mW or 1 mW. In this way the modules can be used in applications where continuous transmission is necessary in all 32 channels. In order to maintain high reliability and stability even in a tough condition for radio, Circuit Design Inc has improved the blocking performance and selectivity of the receiver, to achieve receiver class 1.2 classification as defined in EN300220. Adjacent channel selectivity in band is 60 dB (25 kHz channel spacing) and adjacent band selectivity is 60 dB. Circuit Design Inc, Nagano, Japan. www.circuitdesign.jp
