Radio circuits electronic circuits design projects
Radio circuits electronic circuits design projects and schematics various transmitters, receivers, rf amplifiers, rf boosters and other similar radio circuits.
Very simple, sensitive and high quality AM radio circuit can be make with MK484 monolithic integrated circuit with very few external components.
This MK484 AM radio circuit provides a complete solution including : RF amplifier, Detection and AGC circuit (automatic gain control ), which requires only a few external components to give a high quality AM Tuner.
This fm transmitter electronic project is designed using common electronic parts and 2N2222 transistors. To get a bit of tuning out of the coil you could put a 4-40pF trimmer capacitor parallel over the 1 µH inductor.
The power supply for this mini FM transmitter with transistors ( transmitter ) can be a stabilized 9V power supply or we can use a 9 volts battery.
This long range fm transmitter circuit electronic project is designed using common electronic parts and is capable to transmit signal up to 400 meters .
This long range fm transmitter circuit can be used to supervise a room or to design a wireless microphone . To listen the signal it can be used any Fm radio receiver.
