Abstract

This letter presents a power amplifier (PA) design and network synthesis approach to achieve wideband and efficient performance with a very compact circuit size. A design method is presented in detail to convert a canonical filter-based high-order matching network to the proposed matching configuration with transistor parasitic and packaged elements absorption, and a compact passive network footprint. As a proof of concept, a prototype GaN HEMT PA is implemented. Starting from a fourth-order output network filter, the inductances and capacitance of the filter elements are re-organized to model, and thus absorb the output parasitics of the transistor, leading to a compact footprint with only four transmission lines. The measured results show that the prototype PA achieves an output power of 41.9–44.3 dBm and a 55%–74% drain efficiency, over a record-high decade bandwidth (0.35–3.55 GHz).

超十年带宽高效率紧凑型GaN功率放大器的设计

本文介绍了一种功率放大器(PA)设计和网络合成方法，以非常紧凑的电路尺寸实现宽带和高效性能。详细介绍了一种将基于规范滤波器的高阶匹配网络转换为具有晶体管寄生和封装元件吸收、无源网络占用空间小的匹配结构的设计方法。作为概念验证，实现了GaN HEMT PA原型。从四阶输出网络滤波器开始，滤波器元件的电感和电容被重新组织以建模，从而吸收晶体管的输出寄生，导致占地面积紧凑，只有四条传输线。测量结果表明，原型放大器的输出功率为41.9-44.3 dBm，漏极效率为55%-74%，十进带宽(0.35-3.55 GHz)创历史新高。

期刊介绍： The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
