Hi everyone,
I'm trying to design a schematic for a RF ASK MODULATED DATA TRANSMITTER, as follows schematic link.
Mainly, the schematic is divided in three blocks:
The first is the digital data simulated by the IC 555 generating square wave at 1.18kHz.
The second is the carrier generated by a tank circuit at 10kHz with a buffer opamp to increase the output impedance.
The third is the modulator that based on the data signal controls if the carrier is HIGH or LOW.
So, I thought that adding a antenna at the transistor collector would work, is this right it? I didn't assembled the circuit yet.
If anyone has suggestion to increase the circuit quality, please share.
