10KW CLASS, AM BROADCASTING SEMICONDUCTOR TRANSMITTER USING PULSE WIDTH MODULATION

摘要

The subject innovation is the related to a amplitude modulated medium frequency broadcast transmitter, the output 10KW class using a semiconductor, and the power amplifier on the same eight power amplifier in order to obtain high power at the same time, after the amplitude modulation sikimeuroseo to it and again the high power combining 10KW in the medium-wave broadcast transmitter to obtain a high-power semiconductor,; In order to obtain the amplitude modulation to achieve the same eight power amplifiers subcarriers of 80KHZ in each stage (SUB CARRIER) to a pulse width modulation (PULSE WIDTH MODULATION) was then efficient amplitude modulation hameuroseo uses it as the modulation signal to remove the sub-carrier again,; It relates to a class 10KW medium wave broadcasting transmitter that uses a semiconductor.
