This article proposes a novel validated de-embedding approach to S-parameter measurement. This de-embedding approach benefits from the fully symmetric nature of the designed tapered transmission line test fixture and requires only a Through (THRU) standard. A key point of this approach is solving for a new coefficient RxR_{x} , which is defined to take into account the inherent physical properties of the transmission network. Compared with previous thru-only de-embedding methods, the present approach is applicable to a significantly wider range of frequencies and offers more flexibility in the design of the test fixture. In addition, this approach simplifies multiport configurations compared with traditional complicated calibration methods such as Through, Reflect, Line (TRL). For validation purposes, symmetric two- and four-port tapered THRUs were designed and measured. This novel de-embedding approach is verified by comparison measurements with the classic TRL method or the HFSS simulation and shows a very good agreement.

基于锥形传输线的测量——仅直通去嵌入方法



本文提出了一种新颖的经过验证的去嵌入 S 参数测量方法。这种去嵌入方法得益于所设计的锥形传输线测试夹具的完全对称特性,并且仅需要直通 (THRU) 标准。这种方法的关键点是求解新系数 RxR_{x} ,该系数的定义是为了考虑传输网络的固有物理特性。与以前的仅直通去嵌入方法相比,本方法适用于更广泛的频率范围,并在测试夹具的设计中提供更大的灵活性。此外,与直通、反射、线路 (TRL) 等传统复杂校准方法相比,该方法简化了多端口配置。出于验证目的,设计并测量了对称的两端口和四端口锥形直通。这种新颖的去嵌入方法通过与经典 TRL 方法或 HFSS 模拟的比较测量得到验证,并显示出非常好的一致性。
