Hi all!!!! I need to construct an ultra low cost (less than US$2.50) transmitter. 0dB output power, OOK modulated, stable (maybe SAW stabilized), 433 or 432 MHZ, 2.5 to 3.3V power supply. Need only the Tx circuit (the modulation signal comes ready from another circuit). Low power consumption is a need. Could anyone help me with circuits (practical articles welcome), please?
Have searched through internet but found only ready kits and products selling over US$6.00. The Rx circuit is not a problem. Need only 30m reach. I have large practice with PCB routing but have never routed a RF PCB.
Best regards to all.
