TWO TRANSISTOR FM RECEIVER GENERATOR
TWO TRANSISTOR FM RECEIVER SERIES
Boost Converter LM2587 The LM2587 series of regulators are monolithic integrated circuits specifically designed for flyback.BF199 Transistor has 50mA collector current and 25V Collector-Emitter voltage. It is suitable for use with microcontrollers.ĢN2222, 2N3904, 2N4401, BC337 (Some transistors' pin configuration is different from BC547, check the pin configuration before changing it in a circuit)īF199 is in BF Transistor Series and in TO-92 sheath. It is contained in a TO-92 case designed for medium power applications. The NPN Bipolar Transistor is designed for use in linear and switching applications. The antenna cuts the radio waves and converts them into alternating currents applied to the receiver, and the receiver outputs the desired information.īC547 is an NPN Transistor commonly used in low power amplifier circuits. What are BC547 and BF199? I will explain them to you.Ī radio receiver is an electronic device that receives radio waves and converts the information carrying them into a useful form. The complete schematic of this superheterodyne shortwave receiver is available at google drive.Here is a very simple and effective circuit using only 4 transistors. To receive other stations which including VoA, Radio France, Deutsche Welle, ABC we use our 2 × 12 feet T antenna.įor initial IF transformer tuning we recommended to use a quite large antenna and some powerful station. With small wire antenna, this receiver is capable to receive most of the stations which including CRI, BBC World service, All India Radio, etc. In our testing, we use a TDA2050 audio power amplifier with this receiver. This receiver is designed to work with 9V regulated power supply and it requires an external AF amplifier to drive the headphone or speaker.
For precision tuning, connect small trimmer capacitor with parallel to variable capacitor’s gangs or use mechanical wheel assembly with the variable capacitor. For tuning use Polyvaricon or air variable capacitor. This receiver can be constructing on PCB, breadboard or commonly available veroboard or stripboard. Prototype version of two transistor superheterodyne shortwave receiver. With quite good external antenna this receiver performs similarly to the commercially available shortwave receiver and its audio quality is at a very satisfactory level. This is two transistors and two IF transformer based superheterodyne receiver which is designed to receive 13m to 41m bands.
