Simple FM Receiver Pocket FM Radio by BF184 It is a pocket receiver that I built. The idea was to use a simple receiver, but can be used to escape to 3 times viewed. My previous 6-transistor receiver was more complicated and requires 12 volts. This means that 10 AA batteries. I designed and built acircuit board, and built a small aluminum box [...]
FM IF Subsystem with CA3189E TheCA3189E is a comprehensive FM-IF system designed for high fidelity FM tuners. It includes a three stage FM-IF amplifier/limiter configuration with level detectors for each stage, a double-balanced quadrature FM detector and an audio amplifier that features the optional use of a muting circuit. The advanced circuit design includes desirable special features such as delayed [...]
FM radio with TDA7000 An FM radio on a single chip requiring only a few simple peripheral components. In particular the ship requires only one simple coil and alignment is very easy. The chip includes an RF input stage, mixer, local oscillator, IF amplifier/limiter, phase demodulator, mute detector and mute switch. The output will directly drive a crystal earpiece [...]
synthesizer generates 19-kHz pilot tone for FM baseband signal This Design Idea presents a low-cost method of generating the basic 19-kHz pilot tone. The 19-kHz pilot tone comprises a baseband signal, and the L+R and L–R signals consist of DSBSC (double-sideband-suppressed-carrier) modulation centered at 38 kHz. For a receiver to correctly demodulate the signal, the transmitted pilot tone and L–R signal must synchronize at [...]
Simple FM Receiver by TDA7000 With the TDA 7000 you can build an FM radio with a minimum of components; most of them so easy to manage…like the ceramic capacitors that do not require polarization…and only two resistors. The components you will employ will be of small dimensions and low cost. Even the integrated circuit itself, the TDA 7000, is [...]
FM Receiver 4 Transistor by BF184 This is a pocket sized receiver I built in 1994. The idea was to make a simple but useable receiver running off 3V. My previous 6 transistor receiver was more bulky, requiring 12V. This meant 10 x AA cells. I designed and made a PCB, and constructed a small aluminium case to keep the receiver [...]
FM – AM Regenerative Receiver by 2N2646 The following is a design for a separately quench super regen receiver I first tried in early 1992. It worked far better than any other solid state design, so I built a portable version for use during my commuting from the Blue Mountains to Sydney on the train. Running off 10x AA nicads, this gave [...]
FM Receivers by TL431 – 2N4416 Here is how you make a superregenerative circuit. Choose a regenerative amplifier circuit configuration that requires more current during oscillations than when not oscillating. Adjust the regenerative amplifier to oscillate. Add a small circuit that uses the current of the amplifier to charge a capacitor while oscillations are taking place. Once the capacitor is charged, [...]
FM Stereo Receiver by TEA5711T Let’s begin by soldering a three-pin ceramic filter to the PCB. These three pins will be coming from terminals #11, #12 and #13 of the TEA5711T chip. Next, solder another three-pin ceramic filter to the PCB. These three pins will be coming from terminals #7, #8 and #9 of the TEA5711T chip. Once that is [...]

One Transistor FM Receiver by MPF102 This radio is sensitive enough to tune 20 stations across the FM band, some with volume high enough to drive a small PM speaker. The ability to tune 88.9 MHz and 89.1 MHz is testimony of its selectivity. The signal-to noise ratio rivals that of the better walkman type radios.

FM Radio TDA7088 Receiver The electronic diagram of the monophonic FM receiver made with TDA7088T is shown on Pic.4.12. If built with SMD components it can be placed in a matchbox, altogether with two button-type batteries. The operating principle of this device is given in the previous chapter. The only thing new is a very simple audio amplifier made [...]
6 Transistor Super Regen Receiver by BC548 This little super-regenerative receiver is essentially an AM receiver, with “slope detection” used for FM. By tuning to one side of the carrier, the receiver’s tuned circuit converts FM to AM. The bandwidth is about 200KHz so wideband FM stations can be demodulated by tuning the receiver to the most linear point of the response [...]
BH1417 Stereo PLL FM Transmitter This is the latest BH1417 FM Transmitter design from RHOM that includes a lot of features in one small package. It comes with pre-emphasis, limiter so that the music can be transmitted at the same audio level, stereo encoder for stereo transmission, low pass filter that blocks any audio signals above 15KHz to prevent any [...]
FM Superregenerative Receiver using only two transistors Building an AM receiver is a simple project for a beginner, but building an FM receiver is rather trickier. However, with a little ingenuity we can get away with a very small number of components: our superregenerative Audion receiver uses just two transistors, two coils and a few capacitors. [...]
