This paper presents a high-power Continuous-mode Doherty Power Amplifier (C-DPA) for base-station applications. By utilizing de-embedded models of active devices and allowing the two transistors modulate each other at harmonic frequencies, the proposed C-DPA exhibits improved power, efficiency and bandwidth. Based on the proposed technique, a demonstrating 200 Watt C-DPA was designed over 1.7–2.7...
In this paper, a novel technique is proposed to improve Doherty Power Amplifiers' (DPAs') bandwidth and efficiency by manipulating harmonic components to reshape current and voltage waveforms over a continuous bandwidth. Such operation creates a series of continuous high efficiency modes at each frequency over the band, which is referred as Continuous Mode Doherty Power Amplifier (C-DPA) in this paper...
In this paper, a novel matching structure is introduced to implement accurate impedance matching at intermodulation (IM) frequencies in concurrent dual-band power amplifiers (PAs). Additionally, a concurrent dual-band Doherty power amplifiers (DPAs) architecture featuring Intermodulation impedance tuning (IM tuning) is introduced in this paper. Based on the proposed matching structure and DPA architecture,...
A novel design method of concurrent dual-band power amplifiers (PAs) including impedance tuning at inter-band modulation (IM) frequencies is proposed in this paper. It's shown that the impedances exhibited to the transistor at IM frequencies can affect the performance of a concurrent PA significantly. Thus it is very essential to take IM impedances into account, which can be referred to as IM impedance...
