| Summary: | 碩士 === 國立臺灣大學 === 電信工程學研究所 === 92 === The transmitter architecture with wireless communication system we investigated that is called the polar transmitter. This architecture is different from conventional quadrature transmitter. As we know, any input signal of baseband message is decomposed into magnitude and phase signal, and then goes through envelope modulator and phase modulator respectively. The modulated envelope and phase message signals are combined and amplified by switched-mode power amplifier. In this paper, we are going to focus on the envelope modulator of polar transmitter and the application of wireless mobile handset.
