本文提出了一种新的系统的方法来分析噪声系数(NF)的灵敏度的MMIC低噪声放大器(LNA)的器件结构参数,如栅极凹槽的变化。利用这种新方法制作了一个全单片单平面两级LNA,在50 GHz时具有2.8 dB的极低NF。比较研究表明,在所制造的HEMT的栅极凹陷的变化不会导致在MMIC-LNA的NF的变化。&lt;<ETX>&gt;
This paper proposes a new systematic approach to the noise-figure (NF) sensitivity analysis of MMIC low-noise amplifiers (LNA) regarding device-structure parameters such as gate-recess variation . A full-monolithic uniplanar two-stage LNA with an extremely low NF of 2.8 dB at 50 GHz is fabricated and analyzed using this new method. A comparative study reveals that the gate recess variation in the fabricated HEMTs causes no substantial NF variation in the MMIC-LNAs.<<ETX>>
