Dear All,
I am working on long range(~300m) transmitter and receiver design. Due to the chip limited(the lowest data rate = 4kbps), I would like to use microprocessor's general I/O to send one bit per second(low data rate) on antenna at 1GHz by load modulation(switch MOSFET). I am not sure whether it work or not. Please give me some advice? Is there any other solution suit low data rate to reach long range?
From receiver side, is there any simple circuit(input to microprocessor) to detect this bit per second(low data rate)? I am not sure it is possible or not. Is there any useful link or information about it?
Best Regards,
jerry
