论文摘要
本文介绍了具有低功率阈值（$ p_ {th} $）和sub-db insertion-loss值（$ il^{s.s s} $）的设计方法，以实现基于反射二极管的参数选择性限制器（PFSLS）（$ p_ {th} $）和sub-db insertion insertion-insertion-insertion-insertion-insertion-insertion-insertion-insertion-insertion-insertion-insertion-insertion-loss值（$ iL^{s.s} $）的驱动力级别（$ p_ {in} $ p_ {in} $）。此外，我们介绍通过讨论的方法设计并在FR-4印刷电路板（PCB）上组装的反射性PFSL的测量性能。多亏了其最佳工程动力学，构建的PFSL可以在$ \ sim $ 2.1 GHz左右运行，同时展示记录 - 低$ p_ {th} $（-3.4 dbm）和$ il^{s.s} $（0.94 dB）值。此外，尽管PFSL可以有选择地衰减不希望的信号，功率范围从-3.4 dBm到13 dBm，但即使在更高的$ p_ {in} $值驱动的情况下，它也提供了强大的抑制水平（IS> 12.0 dB），即接近28 dbm。这种测得的性能指标表明，如何通过与传统的芯片尺度制造工艺兼容的组件和系统来利用基于参数的FSL的独特非线性动力学，以提高电磁干扰（EMI）的韧性，即使是针对低功率消费设计的无线无线电，并通过狭窄的动态范围而设计的。
This article describes the design methodology to achieve reflective diode-based parametric frequency selective limiters (pFSLs) with low power thresholds ($P_{th}$) and sub-dB insertion-loss values ($IL^{s.s}$) for driving power levels ($P_{in}$) lower than $P_{th}$. In addition, we present the measured performance of a reflective pFSL designed through the discussed methodology and assembled on a FR-4 printed circuit board (PCB). Thanks to its optimally engineered dynamics, the built pFSL can operate around $\sim$2.1 GHz while exhibiting record-low $P_{th}$ (-3.4 dBm) and $IL^{s.s}$ (0.94 dB) values. Furthermore, while the pFSL can selectively attenuate undesired signals with power ranging from -3.4 dBm to 13 dBm, it provides a strong suppression level (IS > 12.0 dB) even when driven by much higher $P_{in}$ values approaching 28 dBm. Such measured performance metrics demonstrate how the unique nonlinear dynamics of parametric-based FSLs can be leveraged through components and systems compatible with conventional chip-scale manufacturing processes in order to increase the resilience to electromagnetic interference (EMI), even of wireless radios designed for a low-power consumption and consequently characterized by a narrow dynamic range.
