摘要
本文讨论了一种采用直接输入分频电路技术的多尔蒂功率放大器(Doherty power amplifier, DPA),改进了经典DPA的AM-AM性能。所提出的DPA能够根据输入功率控制输入功率的分频比,从而大大提高了峰值放大器的输出能力。ADS仿真结果表明,基于两个飞思卡尔MRF6S27015器件设计的DPA在输入2.35 GHz长期演化信号、输出功率为40.9 dBm时,漏极效率为51.9%,IMD3为-33.6 dBc,与经典DPA相比,漏极效率提高5.8%,IMD3为4dBc。
A Doherty power amplifier employing direct input power dividing technology
A Doherty power amplifier (DPA) using direct input power dividing circuit technology is discussed in this paper, which improves the AM-AM performance of the classical DPA. The proposed DPA is able to control the input power dividing ratio according to the input power, which results in the outputting ability of the peaking amplifier is increased dramatically. The ADS stimulation results show that the designed DPA based on two Freescale MRF6S27015 device achieve 51.9% drain efficiency and -33.6 dBc IMD3 when input long term evolution signal at 2.35 GHz and output power is 40.9 dBm, which improve 5.8% in drain efficiency and low 4dBc in IMD3 compared with classical DPA.
