| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The improvement of efficiency on power amplifiers (PAs) has been a major assignment from dc to microwave region. The class-E and F PAs, overdriven amplifiers with harmonics control are well known scheme to obtain the high efficiency on microwave PA. However, significant deterioration as same as the conventional amplifier is specifically inevitable issue in the linear operation. These facts draw efficiency reduction and modulation inaccuracy on the high backoff modulation such as OFDM. Recently, EER (envelope elimination and restoration) and polar modulation are widely researched as a solution for these issues. In this work, a novel EER transmitter with burst-width modulation driven class-E amplifier system is verified on 64 QAM signal of 2.3GHz. As a result, it is confirmed that basic parameters on PA, EVM and PAE are simultaneously improved. |
