Simple 5 watt frequency modulation transmitter power amplifier circuit

Take the high-frequency oscillation signal of the IF output from the television electromechanical high frequency head as a signal source, the oscillation frequency of the high frequency head itself is very stable, and the BT input voltage is added with an 8V voltage regulation, so as long as the voltage is not In the case of less than 9V, a stable frequency can be output, and the input should be added to the coupling capacitance of a few P. If the third level is large, it can be used in parallel with two three-level pipes, adjust the selected When the frequency circuit is adjusted, the inductive coil is adjusted. This circuit center frequency point is adjacent to 98m, and the resulting frequency is adjusted at the end of 96.5m, R9 should use 100 Euro resistors, it is best to connect the false load, the maximum output time R9 It can be short, the end-level must be refined, and the power supply used when adjusting is preferably a secure power supply. The FM transmitter is a simple communication tool, because it does not require the transfer station and the ground switch station support, It can be effectively mobile communication, so it is well received by people.: 1 time: simple microphone preamplifier circuit composed of MC2830 Next: No smoking warning - Smoke detection simple circuit two copyright and disclaimer All the works of the "Source: Wiume Electronics Market Network" are copyrighted by the Weitu Electronics Market Network.
