Analysis of PIE and T Matching Networks For Low Noise Amplifier (LNA)
This paper presents a analysis of pie and T-matching networks for low noise amplifier using design system
(ADS) software. The matching networks designed used T, and Π matching network consisting of lump reactive element at
the input and output terminal. T-Matching network gives a comparably better results than among of matching networks.
From the analysis results the T-matching network of microwave low noise amplifier (LNA) produced gain (S21) of 19.52 dB
and return loss (S12) of -20.85 dB. The input reflection (S11) and output return loss (S22) are -14.73 dB and -12.07 dB
