| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In an Envelope Pulse Width Modulation(EPWM) transmitter, amplitude of a high PAPR signal such as OFDM is converted to a PWM signal by a delta-sigma(Δ－Σ) modulator. The EPWM signal with the PWM envelope is amplified by a saturation amplifier without causing nonlinear distortion. However, burst-mode EPWM signal requires high speed ON-OFF operation of the saturation amplifier. In addition, a BPF is necessary to suppress quantization noise from Δ－Σ modulator .In this paper, conditions are discussed for high efficiency RF burst-mode amplification with the saturation amplifier and BPF. Total operation of the saturation amplifier and BPF for the RF burst signal is presented. |
