I am trying to implement a project which consists of two circuits. Circuit A receives a 125khz AM signal and modulates it to 433Mhz CC1101 which then uses 2.4Ghz carrier to send at longer distance. Circuit B receives and demodulates the 433Mhz signal back into original 125khz. I am using AS3933 for receiving 125khz LF signal and CC1101 to transmit the signal at higher frequency. The core of the project is Arduino Uno. The signal path I'm hoping is for goes like this:
(Circuit A) 125 kHz -> AS3933 -> Arduino -> 125khz to 433Mhz modulation -> CC1101(2.4Ghz)-> 2.4 GHz -> (Circuit B) CC1101(2.4Ghz)->Arduino-> 433Mhz to 125khz demodulation -> some 125khz signal modulation using coil antenna
I am wondering how do I design modulation/demodulation circuit for 125khz to 433Mhz?
Here are the datasheets:
All help is greatly appreciated!
