- 针对传统功分器尺寸大、带宽窄并且难以用于集成,基于GaAs工艺设计一款超宽带两路等分功分器芯片。芯片采用两节威尔金森结构,用低通Π模型替换四分之一波长微带分支线,实现了功分器宽频带及小型化,芯片尺寸为1.75 mm×0.86 mm,在12～26.5 GHz工作频率范围内,插入损耗小于3.65 dB,回波损耗小于15 dB,隔离度大于17 dB。此外,芯片采用片上通孔金属化工艺保证良好接地,不需要额外接地措施,使用简单方便,背面采用金属化处理,适用于共晶烧结或导电胶粘结工艺。
- Abstract:
- To address the large size, narrow bandwidth, and difficulty in integrating traditional power dividers, an ultra-wideband two-channel equal power divider chip is designed based on the GaAs process. The chip features a two-section Wilkinson structure and utilizes a low-pass Π model to replace the quarter-wavelength microstrip branch line, realizing the broadband and miniaturization of the power divider. The chip size is 1.75 mm×0.86 mm,within the operating frequency range of12-26.5 GHz, the insertion loss is less than 3.65 dB, the return loss is less than 15 dB,and the isolation degree is greater than 17 dB. In addition, the chip adopts an on chip through-hole metallization process to ensure good grounding without the need for additional grounding measures. It is simple and convenient to use, and its back is metalized, making it suitable for eutectic sintering or conductive adhesive bonding processes.
