FM Transmitter Circuit Diagram and Explanation. Connect the components as shown in the Simple FM transmitter circuit below. This is how this simple FM transmitter circuit looks on breadboard. The audio output signal from the microphone is usually small, the first transistor thus performs the job of amplifying that signal to a level good enough.
Stereo FM Transmitter Circuit using IC BA1404 Homemade Circuit Projects
The FM transmitter is a single transistor circuit. In the telecommunication, the frequency modulation (FM) transfers the information by varying the frequency of the carrier wave according to the message signal. Generally, the FM transmitter uses VHF radio frequencies of 87.5 to 108.0 MHz to transmit & receive the FM signal.

An FM (Frequency modulation) circuit represents wireless communication enabled by a BJT or a single transistor. Sound signals in this circuit travel by shifting the carrier wave frequencies depending on the prevailing message signal. FM transmitters operate at a very high carrier frequency and output frequencies of between 87.5 HZ to 108 MHZ.

a) Selection of tank circuit components - L1 and C6: We know the frequency of oscillations is given by. f = 1/ (2โโLC) Here we require a frequency between 88 MHz to 100 MHz. Let us select a 0.2uH inductor. This gives value of C6 to be around 12pF. Here we select a variable capacitor in the range 5 to 20pF.
88108MHz FM Transmitter Circuit Diagram The Circuit
The FM transmitter (Frequency modulation) circuit is made up of a single transistor or a BJT. In wireless communication, the (frequency modulation) FM carries the data or information by changing the frequency of the carrier wave as per the information or a message signal. The FM transmitter achieves the application of (very high frequency) VHF.

Using the FM transmitter is fairly easy providing that an external FM receiver is available. Start by choosing an FM frequency on the radio that is empty (to ensure that your transmitter does not interfere with other stations). Then, feed a signal into the FM transmitter such as the audio output of an MP3 player or an electret microphone circuit.
