我们推出了一款 36 元件单片毫米波栅极放大器。该网格在 U 波段运行,使用赝晶高电子迁移率晶体管 (pHEMT) 作为有源器件。该网格在 44 GHz 时的峰值增益为 6.5 dB。通过改变外部偏振器和调谐板的位置,可以将网格调谐到 44 GHz 至 60 GHz 的工作频率。在 60 GHz 时,网格的峰值增益为 2.5 dB。增益和调谐曲线与理论预测一致。
We present a 36-element monolithic millimeter-wave grid amplifier. The grid operates in the U-band, using pseudomorphic High Electron Mobility Transistors (pHEMTs) as the active devices. The grid has a peak gain of 6.5 dB at 44 GHz. The grid can be tuned to operate from 44 GHz to 60 GHz by changing the positions of external polarizers and tuning slabs. At 60 GHz, the grid has a peak gain of 2.5 dB. Gain and tuning curves are consistent with theoretical predictions.
