Design of High Gain LNA for Wireless Front-End Communication

Estimating the input power is an important task in order to design a Low Noise Amplifier (LNA). In the current study, a survey of actual available power in different wireless communication frequency bands is conductedusing a wideband low gain micro-strip patch antenna. The circularly polarized low gain antenna is designed and simulated using HFSS. A model of the antenna is fabricated and tested on network analyzer and used for the survey of actual available power. Indoor surroundings as well in outdoor surroundings are considered in the present work to exhibit the significant variations. Based on the minimum available power a high gain LNA is designed considering cascode inductive source degeneration topology. The gain is enhanced by incorporating an inter-stage matching element. The results established 28.21 dB Voltage gain with 0.541 dB noise figure.
