Design of Short-wave Multi-frequency Amplitude Modulation Broadcast Transmitter Scheme
This paper researches the design of shortwave multi-frequency AM broadcast transmitter,analyzes the system composition and design principle of the transmitter.It proposes corresponding design schemes and technical parameters for control and protection sub-system,exciter sub-system,amplifier sub-system,filter sub-system,and voltage regulator,providing a strong reference for shortwave AM broadcast transmitter to realize multi-frequency co-broadcasting technology.
