摘要

提出了一种新型四频带正交支路耦合器(BLC)。本文利用四频带阻抗逆变器的T形耦合线段设计了BLC。采用ADS (Advanced Design System)软件对工作频率f1 = 0.66 GHz、f2 = 1.52 GHz、f3 = 2.57 GHz和f4 = 3.44 GHz的BLC进行了设计。选择Rogers 5870基板进行BLC设计。在最大幅值不平衡0.58 dB、最大相位偏差4.33°的情况下，实现了BLC的s参数特性，包括插入损耗、隔离损耗、正交相位和等功率划分，同时保持了4个频段<-10dB的回波损耗和隔离损耗。仿真结果验证了四频段无刷控制器的理论结果。

A quad band quadrature branch line coupler using coupled line sections

A new quad band quadrature branch line coupler (BLC) has been presented in this paper. The proposed BLC has been designed with the help of the T shaped coupled line sections, quad band impedance inverter. The BLC has been designed using Advanced Design System (ADS) software for f1 = 0.66 GHz, f2 = 1.52 GHz, f3 = 2.57 GHz and f4 = 3.44 GHz operating frequencies. The Rogers 5870 substrate has been selected for the BLC design. The BLC's S-parameters characteristics including insertion loss, isolation loss, quadrature phase and equal power division have been achieved with 0.58 dB maximum amplitude imbalance and 4.33° maximum phase deviation while preserved the <-10dB return loss and isolation loss at four frequency bands. The simulated results of the BLC verified the theoretical results of the BLC at four frequency bands.
