Design of D-band amplifier module

摘要:

重构了Ommic公司CGY2191UH芯片模型，建立了一个精确D波段放大器模块模型；并且设计和加工了一种D波段放大器模块验证了模型的准确性。D波段放大器模块模型包括多节波导模型、共面波导?矩形波导过渡模型、金丝键合线等效电路模型以及CGY2191UH芯片模型。通过对模型的分析并基于目前国内成熟工艺，设计和加工了一种D波段放大器模块。测试结果表明，该模块在110 GHz~140 GHz增益大于4.5 dB，其中最大增益在122 GHz为10 dB。增益测试曲线和模型仿真结果吻合，证明了模型的有效性。

Abstract:

The Ommic CGY2191UH chip model is reconstructed to establish a D-band amplifier module model. A D-band amplifier module is designed and fabricated to verify the accuracy of the model. The D-band amplifier module model consists of two waveguide models, two coplanar waveguide-rectangular waveguide transition models, two gold bonding wire models of the equivalent circuit model and a CGY2191UH chip. Based on current domestic technology, a D-band amplifier module is designed and fabricated. The test results show that the module would obtain a gain greater than 4.5 dB in 110 GHz-140 GHz, and the biggest gain at 122 GHz is 10 dB. Gain test curves agree with the model simulation results well, which validates the model.
