amplifier circuit schematic projects Circuit Diagram Circuit and Working. The simple FM transmitter is built around low-power audio amplifier using LM386 (IC1), transistor PN2222A (T1), 30MHz crystal (XTAL1), varactor diode 1SV149 (D1) and a few other components. Inductor L1 is a three-turn coil made with 20SWG wire that has 8mm diameter with half-turn taping. This simple and easy FM transmitter circuit can transmit the input signal gets from the microphone up to the 500-meter range area. Two NPN transistors and some discrete components are used in the circuit. You can use 3v to 12v DC power supply for this circuit. At low voltage, the range of this transmitter will be shorter.
How the FM Transmitter Works. The circuit is powered by a 9V power supply.Transistor Q1 is a high gain audio amplifier that amplifies the sound detected by the electret microphone.The output of Q1 is fed into the frequency modulating circuit created by transistor Q2, inductor L1, and variable capacitor C5.. This is a very high frequency (VHF) circuit, so you will want to use transistors with a

For the wireless spy transmitter circuit everything becomes pretty simple and you just have to hide the transmitter circuit in some suitable place, like under the table, couch, sofa etc. Parts List. R1 = 10K, R2 = 10k, R3, R4 = 27K, R5 = 1.5 M, C1 = 104, C2 = 220uF/25V, T1 = 188, T2 = 187, MIC = electret mic, IC1 = 741,Power = 9 volt battery FM transmitter is a low-power FM radio transmitter that communicates a signal from a sound gadget to a standard FM radio. Ordinarily, we need to make an FM transmitter that is easy to assemble and has a decent range. So here is a basic FM transmitter circuit that contains just a couple of parts and has a long range.
