摘要

设计并制造了一种采用边缘耦合线的定向耦合器，该耦合器在双层PCB板上通过电平衡实现隔离。测量结果表明，在2.5GHz频率下，匹配带宽为16% (-10dB)，具有4dB耦合和34dB隔离。在2.3GHz到3GHz频率范围内，隔离度在31dB到36dB之间变化。

Directional coupler with high isolation bandwidth using electrical balance

A directional coupler using edge coupled lines is designed and fabricated on a two-layer PCB with isolation being achieved through electrical balance. Measured results show 4dB coupling and 34dB isolation at a frequency of 2.5GHz with 16% matching bandwidth (-10dB). Isolation varies between 31dB to 36dB in the 2.3GHz to 3GHz frequency range.
