FM Wireless Microphone Circuit Construction Details ... Let's try to understand how to build a wireless FM microphone circuit. The mic section actually consists of a mini FM transmitter which is so small that literally it can be accommodated in a space of less a square inch and if its made using SMD, it could well be made within an area of 1 square cm. Wireless FM Microphone Circuit ElectroSchematics The circuit uses two integrated circuits from Maxim. IC1 a MAX4467, is an amplifier raising the microphone signal to a level suitable for frequency modulation (FM). IC2 is a voltage controlled oscillator (VCO) with integrated varactor (a.k.a. varicap diode). It is this small that can be integrated in a wireless handheld microphone. FM wireless microphone circuit diagram | ElecCircuit FM wireless microphone circuit diagram. This is a FM Wireless Microphone circuit. Which we add one transistor in the RF amplifier. So this circuit has two resonance circuits and also two trimmers. This cause has the Higher efficiency and transmission far up. FM Wireless Microphone Schematic Design Below is the circuit diagram and PCB layout of FM wireless microphone: The range of frequencies for the FM broadcast band is 90MHz (MHz = Megahertz or 90 million cycles per second). Because the FM microphone has a variable tuned circuit, it can be tuned to a quiet spot on your local FM broadcast band for the best reception. FM Wireless Microphone Circuit Scheme Below is the circuit diagram and PCB layout of FM wireless microphone: The range of frequencies for the FM broadcast band is 90MHz (MHz = Megahertz or 90 million cycles per second).
