The ARTIC is an integrated low power small size ARGOS 3/4 single chip radio.
ARTIC implements a message based wireless interface. For satellite uplink communication, ARTIC will encode, modulate and transmit provided user messages. For downlink communication, ARTIC will lock to the downstream, demodulate and decode it and extract the satellite messages.
The ARTIC can transmit signals in frequency bands around 400MHz and receive signals in the bands around 466MHz, in accordance with the ARGOS satellite system specifications.
The ARTIC is compliant to all ARGOS 3 and ARGOS 4 RX and TX standards. It contains a RF transceiver and frequency synthesiser and a digital baseband modem. ARTIC also contains two on-chip power amplifiers; an efficient high power PA that can deliver 250mW output power to the antenna and a second PA that delivers an output of 0dBm, enabling the use of an external PA. The (de)modulation algorithms run on an on-chip DSP. This software approach allows for retargeting the ARTIC for other applications. The DSP program is retained by an integrated OTP memory.
Internal power management is autonomously handled by ARTIC in order to optimize its current consumption.
The ARTIC can communicate with an external micro-controller using a standard SPI interface.
The complete system with external components is smaller than 1 square inch.
