This article analyzes and traces the design arrangement of the broadband low noise amplifier (LNA) with geometrical varieties in microstrip line structure divulge circa over the linear parameters like gain, noise figure (NF), return loss (RL), and stability of LNA. Firstly, design of LNA utilizing linear microstrip lines after that LNA design with mitering of microstrip lines with same input and output matching networks had been done and give essential comparisons of parameters. All design configuration, measurements, and estimations are conveyed, carried in applied wave research (AWR) microwave office tool. Likewise, the simulations result shows that with mitered (U-bend) microstrip line in band 7.5–10 GHz parameters, input return loss (IRL) is enhanced by critical amount and NF, gain, output return loss (ORL) are improved by minor fraction but stability degrades by small fraction correspondingly. The proposed LNA with mitered microstrip lines will be favorable for the designer and engineers to analyze dissect effect and as investigate the impact from claiming geometric variation about microstrip lines. Purpose of this study is to analyze effect of geometric variation on broadband low noise amplifier instead of components values variation.
