该论文提出了一种频率可重构的毫米波功率放大器，采用主动阻抗合成和非对称非隔离组合器架构，能够在宽频率范围内实现近最优性能。解决了传统功率放大器因输出匹配或组合网络带宽限制而工作频率范围有限的问题。
A frequency-agile mm-Wave power amplifier capable of reconfiguring itself to operate near-optimally over a wide range of tunable frequencies, yet producing output power >22dBm with PAE>20%, is useful for a wide range of applications in reconfigurable communication systems supporting multi-Gb/s over large links to hyper-spectral sensing and imaging. While recent works have demonstrated high efficiency in Watt-level mm-Wave power amplifiers [1-5], most of the architectures operate over a limited frequency range, primarily dominated by the bandwidth of the output-matching or combiner networks. A frequency-agile power amplifier, therefore, needs a widely reconfigurable, yet an efficient output network, which is difficult to achieve with on-chip variable passives due to their poor quality factors in silicon IC processes. In this paper, we present an architecture where an optimal impedance at the output of each unit cell is synthesized exploiting their
