摘要

针对 Ku 波段和 Ka 波段卫星通信 (SATCOM)，介绍并比较了两种基于 SiGe:C 变压器的电流组合功率放大器 (PA)，它们具有不同的参数振荡阻尼能力。进行了节点分析，并通过测量证明了其检测振荡的有效性。在目标频率 18.8GHz 下，无参量振荡功率放大器实现了 22.8dBm 的饱和输出功率 $(P_\{mathrm{sat}})$，功率附加效率 (PAE) 为 37.7%。

Parametric-Oscillation-Free Efficient SiGe:C Power Amplifier Design for Ku-/Ka-Band SATCOM

For Ku- and Ka-Band satellite communications (SATCOM), two SiGe:C transformer-based current-combined power amplifiers (PAs) with different damping capabilities against parametric oscillation are presented and compared. Node analysis is conducted and proves its effectiveness of detecting oscillation by the measurement. At the targeted 18.8GHz, the parametric-oscillation-free PA achieves 22.8dBm saturated output power $(P_{\mathrm{sat}})$ with 37.7% power-added-efficiency (PAE).
