Main exhibits

Data Transmitters and Receivers

Circuit Design’s small and compact transmitters and receivers are multichannel radio modules available with maximum data rate 4800 bps, 128 channels and RF power 10 mW. Available in the 434 and 869 MHz band, they are fully compliant with RED (EN 300 220) with the highest receiver category 1 for 434 MHz.

Data Transceivers

Circuit Design’s multichannel transceiver modules are available in various frequency bands between 419 to 1252 MHz and 2.4 GHz that incorporate direct sequence spread spectrum technology / true receiver diversity. Communication data rate with maximum 19200 bps with RF power ranging between 1 and 50 mW. The 2.4 GHz radio transceiver complies with worldwide standards making it ready for the global market.

Radio Modems

Circuit Design’s radio modems incorporate embedded radio protocol using full command control for module setting and radio communication. Available in 434 MHz band and fully compliant with RED (EN 300 220), the module is also available in 429 MHz band Japanese version. Incorporating FSK/LoRa modulation and error correction, reliable communication at very long range can be achieved with low RF power.

Telecommand

Circuit Design’s multichannel telecommand radio modules contain all the necessary circuits for robust communication of ON-OFF signals. Transmit up to 6 ON-OFF switching signals in the 434 MHz band or 8 ON-OFF signals in worldwide standard 2.4 GHz using frequency hopping spread spectrum. ID pairing between units and multiple use in one area possible.
