Amplitude modulation transmission device

An amplitude modulation transmission device comprising:

• a transmission modulation control unit configured to receive binary digital transmission data, and transform and output the binary digital transmission data in a transition section into a signal in a sinusoidal wave transition form, wherein the transmission modulation control unit outputs a first modulated transmitting signal and a second modulated transmitting signal;
• a first digital-analog conversion unit configured to convert the first modulated transmitting signal into a first analog transmitting signal;
• a second digital-analog conversion unit configured to convert the second modulated transmitting signal into a second analog transmitting signal;
• a power modulation supplier configured to adjust and output a supply power according to the second analog transmitting signal;
• and
• a cascode power amplifier including a common source amplifier to which a carrier signal is input and a common gate amplifier to which the first analog transmitting signal is input, and having a bias power stage to which an output of the power modulation supplier is applied.
