摘要
本文提出了一种新型的采用多层技术的紧凑型90度混合耦合器。为了减小混合耦合器的本征电路面积,采用了紧凑的曲线形结构和多层结构设计。通过详细的三维电磁仿真,对多层结构的形态和结构尺寸进行了设计和研究。测量的插入损耗小于0.4 dB,相位不平衡小于3度,频率范围为380 ~ 520 MHz。外形尺寸小至16.5 mm × 12.2 mm × 1.66 mm。
A Miniaturized P-Band Coupler with Multi-Layer Dielectric and High Performance
This paper presents a new compact 90deg hybrid coupler using multi-layer technology. In order to reduce an intrinsic circuit area of the hybrid coupler, a compact meandered line configuration and a new multi-layer structure design have been adopted. The configuration and structural dimensions of the multi-layer structure were designed and investigated through detailed 3-D electro-magnetic simulations. The measured insertion loss is less than 0.4 dB, and the phase imbalance is less than 3 degree with the frequency range from 380 MHz to 520 MHz. The overall dimension is as small as 16.5 mm times 12.2 mm times 1.66 mm.
