![]() ![]() This has, to the best of the authors' knowledge, not been presented in literature before. It is observed that the LNA gain (S21) is greater than 15.3 dB, NF less than 1.2 dB, Input return loss (S11) is less than -13.3 dB, Output return loss (S22) is less than -17.1 dB over the 400 MHz bandwidth ranging from 2.2 to 2.6 GHz. To build impedance matching circuits of the amplifier smith chart is used. LNA is unconditionally stable for the frequency range of 2.2 GHz to 2.6 GHz. The wireless signal uses advanced adaptive frequency hopping and is highly immune to wireless interference. The amplifier is manually designed using standard methods. The circuit is simulated in the Keysight Advance Design System (ADS). The transistor ATF-21170 Gallium Arsenide Field Effect Transistor (GaAs FET) is used in this work. We tried to keep the length of microstrip lines as minimum as possible. The circuit is designed with the help of single-stub microstrip lines. The paper aims to design a 2.4 GHz LNA having a bandwidth of 400 MHz. The primary goal of LNA design is to lower the Noise Figure and return losses. The research is carried out for the advancement of the LNA. So there is a need for higher bandwidth to transfer data with higher speed. Nowadays in the era of 5G technology, The quality of data that is being transmitted is increased. LNA’s Noise figure (NF) and Scattering Parameters affect the overall performance of the whole receiver circuit. Low Noise Amplifier (LNA) is the most important front-end block of the receiver. The proposed LNA has successfully designed with 14.25 dB forward gain and 1.14 dB noise figure and working stably in the desired frequency. A completed design of the amplifier was optimized using Keysight Advanced Design System (ADS 2020) software. The amplifier is manually designed using conventional techniques, Smith chart was used to do a matching of the input and output of the amplifier. This paper presents a single stage 2.4 GHz LNA design using single-stub microstrip lines with minimum lengths using Agilent ATF-21170. This situation forces the designers to make choices in the design of MW circuits.

Add a Wi-Fi signal amplifier (sometimes called a signal booster) to a router, access point, or Wi-Fi client at the place where an antenna normally connects. The design of a LNA in Microwave(MW) circuit requires the trade-off many significant features such as gain, Noise Figure(NF). Low Noise Amplifier (LNA) circuit is available in the first stage of microwave receiver, and this stage has vital role in minimizing the system noise figure, provide enough gain with sufficient linearity, and assure a stable 50 Ω input impedance at a low power consumption.
