| Abstract(in English) | It is expected that extended Doherty transmitters achieve high power efficiency for signals with large peak power like OFDM. The ideal power efficiency and optimum parameters of the extended Doherty transmitter with class-B bias of both career and peak amplifiers have been analyzed for OFDM signal amplification. However, extended Doherty transmitters with class-AB biased career amplifier are commonly used in order to improve linearity of the output signal. This paper analyzes ideal power efficiency of the extended Doherty transmitter with different operational class amplifiers for OFDM signal amplification. |
