The circuit functions quite like a colpitts oscillator incorporating a tank circuit for the generation of the required oscillations. An fm transmitter is basically a small gadget that can broadcast audio from a source on a selected frequency. The frequency mainly depends on the positioning and the values of the inductor c1 c2 and c3.
Fm transmission is done by the process of audio pre amplification modulation and then transmission.
The frequency mainly depends on the positioning and the values of the inductor c1 c2 and c3. The above shown wireless fm transmitter circuit is basically a small rf transmitter built around a single transistor. The perfect choice for the lower power broadcaster the fm300t is an economical stand alone 300w fm transmitter with a built in audio processor and stereo generator that delivers a consistently high. The fm transmitter is a single transistor circuit.
