摘　　要：为了满足北斗接收机系统集成化,采用成都海威华芯公司0.25μm GaAs赝配高电子迁移率晶体管(PHEMT)工艺,设计了一款工作在北斗L1频段单片微波集成电路(MMIC)低噪声放大器(LNA)。该LNA采用源级串连电感和栅漏端并联负反馈的两级级联电路结构,实现了低噪声高增益匹配,工作频带为1.5~1.6 GHz,漏极电压3.3 V,工作电流为60 mA时,芯片测试结果显示功率增益大于21 dB,噪声系数小于2 dB,在工作频带内输入输出回波损耗优于10 dB,面积为1 mm×2 mm。仿真结果和测试结果有很好的一致性,可用于北斗接收机射频前端。A 1.5-1.6 GHz microwave monolithic integrated circuit(MMIC) low noise amplifier(LNA) was designed using 0.25 μm GaAs pseudomorphic high electron mobility transistor(PHEMT) technology. The LNA realizes low noise and high gain matching by using source-level serially connected inductance and grid-leakage parallel negative feedback circuit, which the operating frequency is 1.5-1.6 GHz, the drain voltage is 3.3 V, and the operating current is 60 mA, the LNA test results show that the power gain reaches more than 21 dB, the noise factor is less than 2 dB, the input-output echo loss is better than 10 dB, and the chip area is 1 mm×2 mm in the operation. The simulation results are in good consistency with the test results, which can be well used in the radio frequency front-end of the beidou receiver.
