Circuit Design offers a range of 10 mW radio data modules for commercial, industrial telemetry, telecommand and radio data communication for battery-powered operation.
Long range (300-1000 m) can be achieved by combining a narrow bandwidth and a low power transmitter with a high sensitivity receiver.
* CDP-01 434 MHz crystal controlled single channel transmitter and receiver. Has narrow band, high sensitivity and low current consumption (18 mA: TX, 10 mA:RX). Best suited for industrial security and telemetry applications.
* CDP-02 434 MHz synthesized multichannel transmitter and receiver with integrated PLL controller and on-board channel selector (32 channels). Has low voltage operation (3 V:TX, 3,6 V:RX).
* CDP-03S 869 MHz single-channel transmitter and receiver for operation in 868-870 MHz European harmonised band. Modules have narrow band, high sensitivity and high reliability in a compact 7,5 cc size.
* STD-402 434 MHz synthesized multichannel transceiver has 64 RF channels within 434 MHz ISM band. Integrated CPU controls automatic channel search and link, encoder and decoder and communication sequence.
