【摘要】 本文设计并制作一款工作频率覆盖210GHz～220GHz的G波段低噪声放大器模块。模块由波导微带转换、低噪声放大器芯片及芯片偏置电路组成。文中对低噪声放大器模块的设计、加工及测试过程进行讨论,并对低插入损耗的波导-微带转换设计关键技术进行详细阐述。波导-微带转换采用E面微带探针激励完成。通过理论分析及电磁场仿真优化后,设计了转换模型并制作实物进行测试。背对背转换在210GHz～270GHz频段内插入损耗小于2.6dB,回波损耗小于-12dB。测试结果表明设计的波导-微带转换具有插入损耗小,工作频段宽的特点。采用此转换制作的低噪声放大器模块在210GHz～220GHz频段范围内增益大于13dB,噪声系数小于8.8dB,达到预期设计指标。更多还原

【Abstract】 A 210～220 GHz G band low noise amplifier module is designed and fabricated in this paper.The module is composed of microstrip-waveguide transition, low noise amplifier MMIC and bias circuit.The process of design,assemble and test is discussed.The key technology of microstrip-waveguide transition using E plane probe is analyzed particularly.The transition model is fabricated and tested after analyzing and optimizing.The back to back insert loss is less than 2.6 dB and the return loss is less than-12 dB over 210～220 GHz.The test result indicates that the transition has the advantage of low insert loss and wide band.The gain of the low noise amplifier module is above 13 dB and the noise figure is below 8.8 dB over 210～220 GHz.The low noise amplifier module achieves the expected target.更多还原
