    29 x FM Transmitters Circuits and Projects

    Browse through a total of 29 fm transmitters circuits.

    Best of FM Transmitter Circuits Here are some DIY FM Transmitter circuits that we have been published on electroschematics.com. This do-it-yourself fm transmitters are pretty easy to build and will give you a good feeling when you’ll hear the music on the radio receiver. Don’t forget to write your comments and post some links if you know good...
    1 Watt FM Transmitter Project This FM transmitter circuit uses four radio frequency stages: a VHF oscillator built around transistor BF494 (T1), a preamplifier built around transistor BF200 (T2), a driver built around transistor 2N2219 (T3) and a power amplifier built around transistor 2N3866 (T4). A condenser microphone is connected at the input of the...
    FM Module with USB Function The FM module with USB function of Vire Silicon.Co Ltd is an excellent miniature FM module with USB input and digital display for functions. It is available as assembled board with remote. The VIRE-FM 01C FM –USB Module is available as ready made assembled board. Its output can be connected to power amplifier or into the...
    MAX2606 VHF FM Transmitter If you want to be independent of the local radio stations for testing VHF receivers, you need a frequency-modulated oscillator that covers the range of 89.5 to 108 MHz — but building such an oscillator using discrete components is not that easy. Maxim now has available a series of five integrated oscillator building blocks in...
    MAX2606 Mini FM Transmitter With MAX2606 we can make a small mono fm transmitter. It is build with MAX2606 and covers at least 20m with 1.5 m long copper wire antenna. You can use this transmitter as an oscillator but change the 1000pF capacitor from the antenna with 15pF. MAX2606 transmitter output power is -10dBm, that means something around...
    BH1417 Stereo PLL FM Transmitter Circuit This BH1417 pll fm transmitter includes features like: pre-emphasis, sound limiter, stereo transmission, low pass filter, pll circuit, fm oscillator and rf output buffer. The sound limiter maintains the same audio level so no distorsions occur, the stereo encoder separates the left and right channel enabling stereo...
    UUS 65 – 73 MHz FM Transmitter A basic UUS 65 73 MHz fm transmitter circuit schematic which can be used as UUS oscillator with no explanation … 65 – 73 MHz transmitter ( oscillator ) circuit components: L1 = 8 t / 0.3mm / 6mm L2 = 8-12 t / 1mm / 15mm / 1mm gap SRF = 60t / 0.2mm / 3mm / ferrite 65-73 MHz transmitter circuit...
    Veronica 1W FM Transmitter Circuit Veronica 1W FM transmitter is easy to build and to operate in FM. Veronica is also known for frequency stability, clean fm signal and uses no integrated circuit. You may want to check this another 1W FM transmitter circuit. Veronica transmitter is equiped with a mini-mixer and so you may forget an external mixer. This consist...
    Foxhunt FM Transmitter Circuit This 2 meter 144 MHz fox hunt transmitter is used in amateur competitions where a hidden transmitter is to be “hunted” using mostly homebrewed receivers and antennas. The foxhunt electronic circuit is the transmitter. It radiates a high quality signal without unwanted harmonics. Transistor T1 and the crystal...
    88 108 MHz FM Transmitter Circuit The most important part of this 88-108 transmitter is the Colpitts oscillator. C3,C4,C5,C6,CD1-CD2 ans L1 determine the transmission frequency. The RF Oscillator circuit has the BF982 MosFet transistor wich is the active part. The others 2 transistors separate the VCO from antenna. FM transmitter circuit diagram The first...
