| Abstract(in English) | Recently, mobile communication is more than half of the power consumption by power amplifier in the transmitter. Therefore, the power amplifier with high efficiency, linearity, low distortion are required. As a method to meet these demands, the authors proposed a transmitter who previously alternately output. However, it was found that the power efficiency is poor compared with the use of high efficiency transmitter and EPWM ,EER. So, this time, the authors suggested Comparison between EPWM and Quadrature Up-Conversion Type Transmitter with Alternate Generation of Positive and Negative Single-bit was compared with EPWM. As a result, EVM, but the results came out better than EPWM, have resulted in power efficiency is inferior to EPWM but beyond the alternating output, also called inferior to EPWM reduction of quantization noise in the adjacent channel. |
