摘要

提出了一种设计宽带多尔蒂功率放大器的新方法。该方法有效地补偿了功率器件的寄生优势分量。该调峰装置不使用传统的Doherty放大器的四分之一波长延迟线,直接连接到Doherty功率组合节点。该方法应用于双输入225 W峰值输出功率的多尔蒂放大器。使用10 MHz带宽7.5 dB峰均功率比(PAPR)测试信号时,测量到的平均漏极效率(DE)为42.7-47.6%,同时在线性化后保持优于- 50 dBc的相邻通道功率比(ACPR)。

A 225 Watt, 1.8-2.7 GHz Broadband Doherty Power Amplifier with Zero-Phase Shift Peaking Amplifier
A new method for designing a broadband Doherty power amplifier has been developed. Using the proposed method, the dominant parasitic components of the power devices are effectively compensated. The peaking device is directly connected to the Doherty power combining node without using the quarter wavelength delay line of the conventional Doherty amplifier. The proposed method is applied to a dual input 225 W peak output power Doherty amplifier. The measured average drain efficiencies (DE) are 42.7-47.6% using a 10 MHz bandwidth 7.5 dB peak-to-average power ratio (PAPR) test signal whilst maintaining better than −50 dBc adjacent channel power ratio (ACPR) after linearization.
