Description
- Application: This is a short transmitter, mainly used in short radio experiments and tests, understand the principle of modulation.
- Structure: Mainly consists of power input, sound amplification, sound modulation, 21MHZ high frequency oscillation, Class C high frequency amplification, 21MHZ low pass filter.
- Power Input: Professional radio transmitter board, C1 to C6 for the filter capacitors, reduce the power supply interference ripples.
- Sound Modulation: Transformer B1 secondary inductance sound voltage superimposed on the DC power, to get the modulation voltage with the change of the sound source.
- High Frequency Oscillation: 21MHZ high frequency oscillation, crystal Y1 in the circuit is a parallel resonance, equivalent to the inductor.
