Circuit Diagram FM Wireless Microphone using C828 Transistor

Robotronicdiagram. - Now, there are many microphone that develop using wireless that change microphone using cable. Using wireless microphone will make mobility of user very nice then using cable microphone.

Wireless microphone develop using FM transmitter. So, this microphone modulated with frequency using FM carrier signal. In here we will show you one of the FM wireless microphone using transistor C828 like in figure 1 below. 

Circuit Diagram

Component List

  1. Mic Condenser 
  2. Resistors
  3. Capacitors
  4. Inductor
  5. Transistor C828

Circuit diagram like in figure 1 above is Circuit Diagram FM Wireless Microphone using C828 Transistor. Resources of the wireless FM microphone circuit is derived from the 1,5 Volt batteries.

Constructed using a single transistor 2SC829 and a few passive components. All capacitors using ceramic materials and resistors using the 1/4 watt to save a FM wireless microphone schematic circuit. Used a single 1.5 Vdc of battery for power supply. Antenna can be used with a cable 0.75 meters of length use copper lines made on pcb. 

Circuit of wireless fm microphone can be made on the of 0.8 x 5 cm size pcb, so small enough to put on the handle body of microphone. Inductor built it using email wire diameter size of 0.5 mm by 3.5 turns. Setting the work frequency of fm wireless microphone made with stretch and tighten the wire coil inductor. Effective range of wireless microphone above can reach 10 meters in the state of LOS (Line Off Sight) or without obstruction to the FM radio receiver.
