| 摘 要： | 文章重点研究基于分立PHEMT器件和HMIC工艺的有源巴伦,该成果可以进一步用于MMIC的设计。在1～2 GHz频率范围内,通过ADS软件对该有源巴伦进行仿真设计,其幅度差在0.17 dB之内,相位差在0.9°之内。利用AutoCAD软件生成PCB版图,采用Rogers4003基片加工。测试结果与仿真比较一致。

| Abstract: | Based on PHEMT and HMIC,a broad active balun which can be used in MMIC in advance is investigated in the paper.The simulation results show that the phase difference of the two balanced ports is less than 0.9° and the amplitude mismatch is less than 0.17 dB from 1 GHz to 2 GHz.The test results of proposed balun using Rogers4003 are agreement with the simulation results. |
