3. Operational Description
This Module able to transmit and receive messages using the SIGFOX network.
This module addresses the RC2 and RC4 zone (North America and Australia).
- Features
> Sigfox up-link and down-link functionality controlled by AT commands
> Temperature sensor
> Ultra-low power consumption
> High performance narrow-band Sigfox
- Time base of the RF frequency
For Sigfox RF frequency, a TCXO(48MHz) is a clock reference.
- Transmission
The Tx path produces a DBPSK-modulated signal. modulate RF signal generated by the synthesizer. The
modulated RF signal is fed to the integrated RX/TX switch and antenna interface and then out of the AX-
SFEU-1-01.
- Receiver
The Rx path is able to receive 905.2MHz, 922.3MHz signal and the noise amplifier is built in the inside of
the chip, it amplifies the received signal by the low noise amplifier according to the receiving intensity, and
the amplified signal is converted into the digital signal through the ADC, Packets will be interpreted.
