Over years we have developed a number of FM transmitter circuits with various aspects. Today I thought of listing all of them here as a single web page, so anyone can easily navigate through all the radio transmitter circuits and its schematic diagrams. For first time readers- What is an FM transmitter An FM transmitter […]
Everyone is a newbie when they first start. In electronics, one of the best and satisfying things to create is an FM transmitter. This is maybe just me but it is still fun to create an FM transmitter even for a pro. So here is a very simple circuit to create an FM transmitter. Two transistor
PLL Stereo FM transmitter circuit How cool will it be if you can create a gadget that can transmit audio from your phone to your home stereo wirelessly? That’s exactly what we tried with this project, we were trying to create an FM transmitter for home use. There are such gadgets available to buy in
Stereo FM transmitter circuit using BA1404. Notes. A high quality stereo FM transmitter circuit is shown here. The circuit is based on the IC BA1404 from ROHM Semiconductors. BA1404 is a monolithic FM stereo modulator that has built in stereo modulator, FM modulator, RF amplifier circuitries. The FM modulator can be operated from 76 to
Description. A very stable and simple FM transmitter circuit is given here. With a matching antenna, this transmitter can attain a range of around 200 meters. I assembled this transmitter few years and got very good results. Let us see how the circuit works. A condenser microphone (K1) is used to pick the sound to
In this project, we learn how to create a high range FM transmitter, which has the range of 2 kilo meter (2KM) radius. This is basically a simple DIY hobby circuit and you can try it in your home with minimal components. Start building this high range FM transmitter and see how your output comes.
Description. Here is the circuit diagram of an FM transmitter using the IC UPC1651. UPC1651 is a wide band UHF Silicon MMIC amplifier. The IC has a broad frequency response to 1200MHz and power gain up to 19dB.The IC can be operated from 5V DC. The audio signals picked by the microphone are fed to
We have opened an online store where 4 very good books on basic electronics are kept for sale. You can read the detailed reviews and authors profiles and buy the book. Books from renowned authors like Forrest M Mims, Charles Platt, Harry Kybett, and Earl Boysen are included. Check it out here:-Â 4 GREAT BOOKS TO
Description. This is a simple, but very useful circuit that can be used to transmit telephone conversations. When the telephone receiver is on hook the voltage across the lines will be about 48 volts. The preset R7 is so adjusted to obtain a 24.7 V across between the cathode of D2 and ground. At this
Description. Here is the circuit diagram of an easy to build long range AM transmitter circuit based on three transistors.With correct tuning and a matching antenna, the transmitter can deliver signals up to a distance of 2 kilometers. The audio signal to be transmitted is given to the base of the transistor Q1 via the
The above video claims you can make a pocket size FM radio station and the highlight is you dont need an antenna to do this. A small battery is enough to power and it will last for 5 to 7 hrs. This small battery powered FM radiostation even dont need a antenna to broadcast your
Description. With this compact FM adaptor circuit plugged into the audio out of your cassete player or i Pod out put,you can listen your favorite music on your car stereo.This circuit is very useful if your car stereo doesnot have an auxillary in socket.The circuit is nothing buy an short range  FM transimitter. The FM
Description. The IR to RF transmitter circuit given here can convert the IR signals from your remote to RF signals to long distances. The circuit given here is a good one for extending the range of your IR remote.Also such systems does not need a line of sight since RF signals are used. The transmitter
Description. Here is the circuit diagram of a versatile FM transmitter that doesn’t have a coil. The circuit is simple and easy to assemble. The gate N1 acts as a buffer for strengthening the signals from the condenser microphone. The inverter N2 with its associated components forms a radio frequency oscillator in the FM region.The
Description. A simple telephone transmitter circuit that is ideal for transmitting the telephone conversation through small distances.The circuit is very simple and uses only few components.The entire circuit can be easily included in the telephone itself or in the junction box.The circuit is powered from the telephone line itself. The transistor Q2 is wired as
Description. The circuit presented her will transmit a audio tone in the FMÂ band. The circuit can be used as a tracking signal transmitter or a remote control transmitter. The circuit uses only easily available components and any one can build this. The transmitter has a range of 100m @ 9V supply, with a matching
Description. Here is the circuit diagram of the simplest FM transmitter using a transistor. Great performance or range is not guaranteed here, because this is an elementary design. General purpose radio frequency transistor BF 494 (Q1) is used here for obtaining FM modulation. A condenser mic is used here to pickup the sound. The condenser
Single chip FM transmitter An FM transmitter is a device that can transmit audio from an audio device as a radio signal. Doing so allows the audio to be picked up and played by an FM radio in the transmitter’s range. The FM (frequency modulation) device allows the waves to move in predefined frequencies so
In this project, let’s learn how to make a simple “Long-range FM transmitter” at a low cost using minimal components. As you can see in the diagram, the circuit is simple, easy to build and test. Let’s begin to build our long-range FM transmitter. How To Build a Long Range FMÂ Transmitter The use of transmitters
