摘要

这项工作介绍了垂直无焊同轴连接器在2.92 mm和1.85 mm标准下的应用,工作频率高达67 GHz。优化的PCB封装设计,结合广泛使用的射频基板,最大限度地减少接口反射。2.92 mm连接器的回波损耗在30ghz范围内大于20db, 1.85 mm连接器的回波损耗在60ghz范围内大于15db。每个连接器的去嵌入插入损耗在40 GHz时不超过0.5 dB,在67 GHz时不超过0.75 dB。差分宽带放大器和超宽带天线的封装和测量作为实际演示,显示只有轻微的性能下降超过感兴趣的全带宽。

Optimization of PCB Transitions for Vertical Solderless Coaxial Connectors up to 67 GHz
This work presents the application of vertical solderless coaxial connectors for the 2.92 mm and 1.85 mm standards operating up to 67 GHz. Optimized PCB footprints are designed to minimize the interface reflections in conjunction with a widely available RF substrate. A return loss above 20 dB up to 30 GHz for the 2.92 mm connector and above 15 dB up to 60 GHz for the 1.85 mm connector is achieved. The de-embedded insertion loss per connector does not exceed 0.5 dB at 40 GHz and 0.75 dB at 67 GHz, respectively. A differential wideband amplifier and an ultra-wideband antenna are packaged and measured as practical demonstration, showing only a slight decrease in performance over the full bandwidth of interest.
