摘要: 基于南京电子器件研究所的100 nm GaN高电子迁移率晶体管 (HEMT)工艺,研制了6~18 GHz宽带低噪声放大器。低噪声单片电路采用了三级结构,偏置电压为12 V,电流约为70 mA时,在6~18 GHz频带内噪声系数小于1.7 dB,增益大于25 dB,驻波比小于2,1 dB增益压缩点输出功率带内最小值约为10 dBm。前两级采用电流复用结构,降低了功耗;后级采用并联反馈结构,改善带内增益平坦度。芯片尺寸为2.0 mm × 1.35 mm。

Abstract: Based on 100 nm GaN high electron mobility transistor(HEMT) technology of Nanjing Electronic Devices Institute, a 6-18 GHz low noise amplifier(LNA) was designed and fabricated. The low noise monolithic circuit has been designed using a 3-stage topology. Under the condition of 12 V voltage and 70 mA current,measured results show that the noise figure is below 1.7 dB within the bandwidth of 6-18 GHz, the small signal gain is higher than 25 dB, voltage standing wave ratio is less than 2, and output power at 1 dB gain compression point is more than 10 dBm. Current reused technology were adopted by the first two stage, which decreased the DC consumer; the last stage used parallel feedback structure to improve the gain flatness. The chip dimension is 2.0 mm×1.35 mm. Keywords: GaN;broadband;low noise amplifier.

Key words: GaN, broadband, low noise amplifier
