15W FM RF Amplifier with 2SC2539

This the Good Quality FM transmitter for your stereo or any other amplifier gives you a pretty good signal strength up to a range of 500 metres having a power output of about 200 mW. This circuit can be operated with a 9V battery. The audio-frequency modulation stage is constructed close to transistor BF494 (T1), . By working with only a small han
15W FM RF Amplifier with 2SC2539 - schematic

dfull of parts you can assembled this kind of reliable FM Amplifier. It runs with only 1 UHF/VHF type transistor, MFE201. This amplifier will pull in all distant FM stations clearly. The circuit is configured as a common-emitter tuned RF pre-amplifier wired around VHF/UHF transistor MFE201. You will find. Here the SW transmitter circuit based on IC BEL1895. This particular transmitter circuit works in shortwave HF band (6 MHz to 15 MHz), and can be applied for shortrange communication and for educational purposes. The circuit is composed of a mic amplifier circuit, a variable frequency oscillator, and modulation amplifier stages. Transistor T1 (BF195) is. Easy FM tracking transmitter project :). The circuit designed by Tony van Roon, and here the FM tracking transmitter diagram: Components List: R1 = 10K C1 = 100uF/10V C2 = 10nF C3 = 4-40pF trimmer capacitor C4 = 4. 7pF IC1 = LM3909 Q1 = 2N3904 NPN transistor LED1 = Red LED/or another color as you. This diagram is a schematic diagram of RF amplifier circuit. The circuit will amplify the RF signal about 10 times, 100mW input power to 1. 3W output power. It use a general NPN RF transistor 2SC1970. You may apply other transistors, for example 2N442. Circuit Diagram: Circuit Works: RF system and specially in RF amplifiers, this.
