Comparitive Study of Modfet Based Low Noise Amplifier Design In The Bandwidth Of 6 Ghz

摘要

Low noise amplifier is vital in the design of receivers at microwave frequencies. In this paper , the performance of HEMT Low noise amplifier is analyzed at 2.4 GHz within a bandwidth of 6 GHz, FR4 substrate is chosen and Noise figure , Gain are considered as the performance parameters for the comparison. C4 based model obtained by parametric analysis is compared with various other designs in the 6 GHz bandwidth. It is observed that the noise figure and gain values of C4 based design are 0.263 dB and 15.317 dB, which are better when compared with other models.The simulation is carried out using ADS software and performance parameter variation with respect to frequency was studied. The layout of the design is obtained using ADS momentum......
