Stripline technology is considered among the most commonly used guiding structures in various applications due to its low cost, low profile, and power-handling capability. The measurement of stripline structures typically requires coaxial connections with good performance. This letter presents a field-replaceable stripline transition enabling both the measurement and low-profile connection simultaneously. The proposed design is set to operate with good performance up to 20 GHz and is only limited by the used SubMiniature version A (SMA) connector. We use a Teflon seal to ensure compatibility with both the standard coaxial connectors and the low-profile direct connection. The innovatively designed structure provides a matching level beyond 20 dB and an insertion loss of 0.2 dB/inch for the back-to-back configuration. An experimental prototype of the design is fabricated and measured, for which a good agreement between measured and simulated response is observed.

带宽为 20:1 的超宽带末端发射同轴到带状线过渡


带状线技术因其低成本、薄型和功率处理能力而被认为是各种应用中最常用的引导结构之一。带状线结构的测量通常需要具有良好性能的同轴连接。这封信提出了一种可现场更换的带状线过渡，可同时实现测量和薄型连接。拟议的设计可在高达 20 GHz 的频率下以良好的性能运行，并且仅受所使用的超小型 A 版 (SMA) 连接器的限制。我们使用聚四氟乙烯密封件来确保与标准同轴连接器和薄型直接连接的兼容性。创新设计的结构为背靠背配置提供了超过20 dB的匹配电平和0.2 dB/英寸的插入损耗。制造并测量了该设计的实验原型，观察到测量响应与模拟响应之间具有良好的一致性。
