This letter presents the design approach for a compact, single-stage, wideband MMIC power amplifier. A method is proposed to compensate for the output capacitance of the active device over a frequency range as wide as possible, with minimum impact on the achievable output power, which leads to a two-element compensating network. A three-section transformer is then adopted for a real-to-real transformation. The CW characterization shows the output power higher than 32 dBm and the drain efficiency between 35% and 45%, over a fractional bandwidth of 148%, from 3 to 20 GHz.

通过C _OUT补偿策略设计3–20 GHz GaN MMIC功率放大器

这封信介绍了一种紧凑的单级宽带MMIC功率放大器的设计方法。提出了一种在尽可能宽的频率范围内补偿有源器件的输出电容的方法，并且对可实现的输出功率的影响最小，这导致了两个元件的补偿网络。然后采用三段式变压器进行真实到真实的转换。CW表征表明，在3至20 GHz的148％的分数带宽上，输出功率高于32 dBm，漏极效率在35％至45％之间。
