dc.description.abstract | Low noise amplifier (LNA) is one of the basic building blocks of any communication system. The purpose of the LNA is to amplify the received signal to acceptable levels with minimum self-generated additional noise. The design of a LNA in Radio Frequency circuit requires many important parameters such as: gain, noise figure, stability factor (K), power consumption and complexity. This situation forces designers to make choices in the design of RF circuits.
In this work, the transistor BFP420 will be used for the target 3.1 – 3.5 GHz LNA designing. The designed specifications for desired LNA are: Gain ≥ 8 dB, NF ≤ 3 dB, S11 & S22 ≤-12dB, input & output impedances around 50 ohms, K > 1. The design simulation process is done using the software named Advance Design Systems (ADS). | en_US |
