| Abstract(in English) | Medium wave vacuum tube transmitter has been changed from grid modulation type to the plate modulation. High efficiency transmitter adopted third harmonics carrier with the amplification in the transmitter. The Solid state transmitter come into action to the PWM (pulse width modulation) for the modulation amplifier. Lately almost medium wave transmitters are adopted the digital processing type which combined multi PAs (Power Amplifier) by using tandem combiner. This paper discussed the liability management for the system testing method compare with the vacuum tube and the digital processing large power medium wave transmitters. |
