摘要

本文研究了以10.40 GHz为中心频率，工作在10.00 ~ 10.5 GHz频段的3cm波段的不同低噪声放大器的设计。该放大器采用GaAs HEMT A-TF 36077设计，在反馈网络中加入不同的无源元件，是提高潜在不稳定器件稳定性和使其无条件稳定的技术之一。结果表明，采用电阻和电感串联反馈网络的LNA设计具有更强的抗扰性。该设计的噪声系数为1.43 dB，功率增益为21.654 dB。本文对LNA设计进行了比较分析。

LNA Design for 3 cm Band Applications

This work deals with the designing of different low noise amplifiers for 3 cm band application which operates in 10.00 to 10.5 GHz frequency band with 10.40 GHz as the center frequency. The amplifier is designed using GaAs HEMT A–TF 36077 with different passive components in the feedback network which is one of the technique to improve stability of potentially unstable device and make it unconditionally stable. It is observed that the noise immunity is more in LNA design in which feedback network with a resistor and inductor in series is used. This design resulted in noise figure of 1.43 dB and power gain of 21.654 dB. The comparative analysis of the LNA design is discussed in this paper.
